Visualizing Diurnal Population Change in Urban Areas for Emergency Management  

SciTech Connect

There is an increasing need for a quick, simple method to represent diurnal population change in metropolitan areas for effective emergency management and risk analysis. Many geographic studies rely on decennial U.S. Census data that assume that urban populations are static in space and time. This has obvious limitations in the context of dynamic geographic problems. The U.S. Department of Transportation publishes population data at the transportation analysis zone level in fifteen-minute increments. This level of spatial and temporal detail allows for improved dynamic population modeling. This article presents a methodology for visualizing and analyzing diurnal population change for metropolitan areas based on this readily available data. Areal interpolation within a geographic information system is used to create twenty-four (one per hour) population surfaces for the larger metropolitan area of Salt Lake County, Utah. The resulting surfaces represent diurnal population change for an average workday and are easily combined to produce an animation that illustrates population dynamics throughout the day. A case study of using the method to visualize population distributions in an emergency management context is provided using two scenarios: a chemical release and a dirty bomb in Salt Lake County. This methodology can be used to address a wide variety of problems in emergency management.

Soiling by atmospheric aerosols in an urban industrial area  

Science Conference Proceedings (OSTI)

The gradual and progressive soiling of structures exposed to the atmosphere is commonplace. Material soiling results from the deposition of atmospheric aerosols. Both wet and dry deposition occurs. The particle size and the orientation, exposure and roughness of the surface determine the dominant deposition mechanisms. Wet deposition is not an important cause of surface soiling, but precipitation removes particles from a surface. Aged atmospheric particles are characterized by a bimodal size distribution of coarse and fine particles. Coarse particles tend to be inactive chemically and are removed by washout and runoff. A primary cause of building soiling in urban areas has been attributed to the fine-particle mode. When fine particles contain carbon they tend to be black, and adhere more tenaciously to surface than do course particles. Elemental carbon is usually 10-20 percent of the urban fine aerosol mass, and vehicular emissions, particularly diesel emissions, are the major source of urban black smoke. The soiling of buildings occurs over the years from fine particle deposition and is associated with low atmospheric concentrations. This paper describes the influences of particle size and rainfall on the deposition, and on the soiling of surfaces with different surface glosses, orientations and exposures.

Application of district heating system to U. S. urban areas  

DOE Green Energy (OSTI)

In the last few decades district-heating systems have been widely used in a number of European countries using waste heat from electric generation or refuse incineration, as well as energy from primary sources such as geothermal wells or fossil-fired boilers. The current world status of district-heat utilization is summarized. Cost and implementation projections for district-heating systems in the U. S. are discussed in comparison with existing modes of space conditioning and domestic water heating. A substantial fraction, i.e., up to approximately one-half of the U.S. population could employ district-heating systems using waste heat, with present population-distribution patterns. U.S. energy usage would be reduced by an equivalent of approximately 30 percent of current oil imports. Detailed analyses of a number of urban areas are used to formulate conceptual district energy-supply systems, potential implementation levels, and projected energy costs. Important national ancillary economic and social benefits are described, and potential difficulties relating to the implementation of district-heating systems in the U.S. are discussed. District-heating systems appear very attractive for meeting future U.S. energy needs. The technology is well established. The cost/benefit yield is favorable, and the conservation potential is significant. District heating can be applied in urban and densely populated suburban areas. The remaining demand, in rural and low-population-density communities, appears to be better suited to other forms of system substitution.

Real-time modeling of complex atmospheric releases in urban areas  

Science Conference Proceedings (OSTI)

If a nuclear installation in or near an urban area has a venting, fire, or explosion, airborne radioactivity becomes the major concern. Dispersion models are the immediate tool for estimating the dose and contamination. Responses in urban areas depend on knowledge of the amount of the release, representative meteorological data, and the ability of the dispersion model to simulate the complex flows as modified by terrain or local wind conditions. A centralized dispersion modeling system can produce realistic assessments of radiological accidents anywhere in a country within several minutes if it is computer-automated. The system requires source-term, terrain, mapping and dose-factor databases, real-time meteorological data acquisition, three-dimensional atmospheric transport and dispersion models, and experienced staff. Experience with past responses in urban areas by the Atmospheric Release Advisory Capability (ARAC) program at Lawrence Livermore National Laboratory illustrate the challenges for three-dimensional dispersion models.

Fire initiation and spread in urban areas due to nuclear attack  

SciTech Connect

Calculation of fire development in urban areas is a critical step in estimating the global effects of nuclear warfare with regard to smoke production and transport. As part of the first phase of a program to improve our ability to calculate fire starts and spread in urban areas, we have performed a parameter sensitivity analysis using the three codes originally developed for civil defense planning by the IIT Research Institute. We have added graphics and made slight improvements to the codes and applied them to the representation of the San Jose urban area used in the Five-City Study of the late 1960s. For a chosen reference attack scenario, we have varied parameters and compared the results to those of a representative baseline case. The parameters varied included: atmospheric visibility, lowest of the various critical ignition energies of window coverings, shading of windows by trees and awnings, extent of blast extinguishment of fires, secondary ignitions, window glass transmittance, specific firebrand generation rate, firebrand distribution range, windspeed, building densities, specific fuel loadings, and window sizes. 13 references, 10 figures, 5 tables.

Alternative energy facility siting policies for urban coastal areas: executive summary of findings and policy recommendations  

SciTech Connect

An analysis was made of siting issues in the coastal zone, one of the nation's most critical natural resource areas and one which is often the target for energy development proposals. The analysis addressed the changing perceptions of citizens toward energy development in the coastal zone, emphasizing urban communities where access to the waterfront and revitalization of waterfront property are of interest to the citizen. The findings of this analysis are based on an examination of energy development along New Jersey's urban waterfront and along the Texas-Louisiana Gulf Coast, and on redevelopment efforts in Seattle, San Francisco, Boston, and elsewhere. The case studies demonstrate the significance of local attitudes and regional cooperation in the siting process. In highly urbanized areas, air quality has become a predominant concern among citizen groups and an influential factor in development of alternative energy facility siting strategies, such as consideration of inland siting connected by pipeline to a smaller coastal facility. The study addresses the economic impact of the permitting process on the desirability of energy facility investments, and the possible effects of the location selected for the facility on the permitting process and investment economics. The economic analysis demonstrates the importance of viewing energy facility investments in a broad perspective that includes the positive or negative impacts of various alternative siting patterns on the permitting process. Conclusions drawn from the studies regarding Federal, state, local, and corporate politics; regulatory, permitting, licensing, environmental assessment, and site selection are summarized. (MCW)

Atmospheric deposition of polycyclic aromatic hydrocarbons in an urban and a suburban area of Korea from 2002 to 2004  

SciTech Connect

Atmospheric bulk samples (wet and dry) were collected monthly during 2002 to 2004 from an urban and a suburban area in Korea for assessment of depositional flux and seasonal variations in the concentrations of polycyclic aromatic hydrocarbons (PAHs). PAH depositional flux ranged from 64.1 to 610 {mu} g/m{sup 2}/y for the urban area and from 65 to 460 {mu} g/m{sup 2}/y for the suburban area. The fluxes of PAHs measured in this study were comparable with those reported for urban and suburban areas in other countries. The fluxes of particulates and PAHs were higher in winter than in summer, consistent with the greater per capita consumption of fossil fuel in winter than in summer. Ambient temperature played a major role in the seasonal variability in PAH fluxes. Photochemical degradation of PAHs appears to occur during the summer months. The relationship of PAH depositional fluxes with major air pollutants, such as ozone, sulfur dioxide, carbon monoxide, nitrogen dioxide, and presence of particulate matter up to 10 {mu} m in size (PM10), was also investigated. Dominant PAH compounds in both the urban and the suburban locations were benzo(g,h,i)perylene, pyrene, and indeno(1,2,3-c,d)pyrene. Based on the PAH diagnostic ratios and a factor analysis, the major sources of PAHs in the urban and the suburban regions were found to be similar. Diesel exhaust, coal combustion, and gasoline emissions contributed predominantly to atmospheric PAH contamination.

Survey on Cooling Costs and Related Factors for Apartments in an Urban Area of Osaka  

E-Print Network (OSTI)

A questionnaire survey was carried out to assess cooling behaviors and cooling costs for 290 apartments in an urban area. 1) Cooling costs are strongly related to the number of air conditioners, the months of occupation, and the air conditioner usage frequency during sleep. Lifestyle and ecological interest do not decrease costs. 2) Target temperatures of air conditioning are strongly related to the air pollution outdoors, and to the frequency of window opening. Cooling temperatures are affected by the residents' constitution. 3) Both cooling temperature and air-conditioner use frequency are higher for residents worried more about dew, humidity, odors, and mold. 4) Air-conditioner use frequency is higher for residents who are annoyed by glances from outside and for those with a higher preference of outdoors. 5) South openings are related to the lower cooling costs and higher cooling temperatures, whereas west openings are related to higher cooling costs.

A shallow water model for dense gas simulation in urban areas  

SciTech Connect

Large quantities of toxic chemicals are stored at industrial facilities and transported around the country via train and truck. In the event of an accidental release, many of these chemicals are released as heavier-than-air gases that stay low to the ground as they are transported by the wind . Breathing height concentrations can remain high due to reduced vertical mixing and hazard zone coverage area can be larger due to near-source gravitational slumping . A number of fast-response dense gas dispersion models have been developed and are routinely used to deal with heavier-than-air releases over unobstructed terrain. If a release were to occur in a built-up environment, however, the effects of buildings and other obstacles will significantly alter the initial spreading, the transport direction, and the amount of mixing of the dense gas cloud . We have developed a new fast-running dense gas dispersion model that is intended for handling releases in cities and at large industrial facilities. In this paper we describe the scheme employed and how the model has been integrated into the Quick Urban & Industrial Complex (QUIC) dispersion modeling system.

Modeling urban growth and land use/land cover change in the Houston Metropolitan Area from 2002 - 2030  

E-Print Network (OSTI)

The Houston-Galveston-Brazoria Consolidated Metropolitan Statistical Area (Houston CMSA) has experienced rapid population growth during the past decades and is the only major US metropolitan area with no zoning regulations. We use SLEUTH, a spatially explicit cellular automata model, to simulate future (2002-2030) urban growth in the Houston metropolitan area, one of the fastest growing metropolises in the United States during the past decades. The model is calibrated with historical data for the period 1974-2002 that are extracted from a time series of satellite images. The dataset consists of four historical urban extents (1974, 1984, 1992, 2002), two land use layers (1992, 2002), five transportation layers (1974, 1984, 1990, 2002, 2025), slope layer, hillshade layer, and excluded layer. Future growth patterns are predicted based on growth coefficients derived during the calibration phase. After calibrating the model successfully, the spatial pattern of urban growth of the Houston CMSA for the period from 2002 to 2030 is predicted. Within SLEUTH, growth in the Houston CMSA is predominately "organic" with most growth occurring along the urban/rural fringe. Projected increases in urban area from 2002 to 2030 parallel projected increases in population growth within the Houston CMSA. We design three specific scenarios to simulate the spatial consequences of urban growth under different environmental conditions. The first scenario is to simulate the unmanaged growth with no restrictions. The second scenario is to project the moderate growth trend by taking into consideration environmental protection, specifically for agricultural areas, forests and wetlands. The last scenario is to simulate the managed growth with maximum environmental protection. Adjusting the level of protection for different land cover types was found to markedly affect the land use changes in the Houston CMSA. Without any protection on resource lands, Houston CMSA is estimated to lose 2,000 km2 of forest land by 2030, about 600 km2 of agricultural land, and approximately 400 km2 of wetland. Approximately half of all resource land could be saved by the third scenario, managed growth with maximum protection.

Dose Modeling Evaluations and Technical Support Document For the Authorized Limits Request for the DOE-Owned Property Outside the Limited Area, Paducah Gaseous Diffusion Plant Paducah, Kentucky  

SciTech Connect

Environmental assessments and remediation activities are being conducted by the U.S. Department of Energy (DOE) at the Paducah Gaseous Diffusion Plant (PGDP), Paducah, Kentucky. The Oak Ridge Institute for Science and Education (ORISE), a DOE prime contractor, was contracted by the DOE Portsmouth/Paducah Project Office (DOE-PPPO) to conduct radiation dose modeling analyses and derive single radionuclide soil guidelines (soil guidelines) in support of the derivation of Authorized Limits (ALs) for 'DOE-Owned Property Outside the Limited Area' ('Property') at the PGDP. The ORISE evaluation specifically included the area identified by DOE restricted area postings (public use access restrictions) and areas licensed by DOE to the West Kentucky Wildlife Management Area (WKWMA). The licensed areas are available without restriction to the general public for a variety of (primarily) recreational uses. Relevant receptors impacting current and reasonably anticipated future use activities were evaluated. In support of soil guideline derivation, a Conceptual Site Model (CSM) was developed. The CSM listed radiation and contamination sources, release mechanisms, transport media, representative exposure pathways from residual radioactivity, and a total of three receptors (under present and future use scenarios). Plausible receptors included a Resident Farmer, Recreational User, and Wildlife Worker. single radionuclide soil guidelines (outputs specified by the software modeling code) were generated for three receptors and thirteen targeted radionuclides. These soil guidelines were based on satisfying the project dose constraints. For comparison, soil guidelines applicable to the basic radiation public dose limit of 100 mrem/yr were generated. Single radionuclide soil guidelines from the most limiting (restrictive) receptor based on a target dose constraint of 25 mrem/yr were then rounded and identified as the derived soil guidelines. An additional evaluation using the derived soil guidelines as inputs into the code was also performed to determine the maximum (peak) dose for all receptors. This report contains the technical basis in support of the DOE?s derivation of ALs for the 'Property.' A complete description of the methodology, including an assessment of the input parameters, model inputs, and results is provided in this report. This report also provides initial recommendations on applying the derived soil guidelines.

The gated community: residents' crime experience and perception of safety behind gates and fences in the urban area  

E-Print Network (OSTI)

The primary purpose of the study is to explore the connections between residents' perception of safety and their crime experience, and the existence of gates and fences in multi-family housing communities in urban areas. For cultivating discussions regarding the connections between gated community territory, safety, and crime experience, this study classifies apartment communities according to the conditions of their gating and fencing: gated communities, perceived gated communities, and non-gated communities. It investigates residents' perceptions of safety and their opinions and managers' opinions on gated territory and safety. The major findings from the surveys are: Residents felt safer in gated communities than in non-gated communities. Residents' perceptions of safety in perceived gated communities were similar to those in gated communities. These results reflected the territoriality issue for improving residents' perceived safety in apartment communities. Residents' perceptions of safety in architectural spaces showed that residents' fear of crime in public and semi-public spaces must first be addressed in order to ease residents' fear of crime in an apartment territory. The reality of crime in apartment communities differed from residents' perceptions of safety. Gated community residents reported a higher crime rate than nongated community residents. In addition to gates and fences that define apartment territory, such elements as patrol services, bright lighting, direct emergency buttons, and visual access to the local police were indicated as the important factors for improving residents' perceived safety. Some architectural factors and demographic factors exhibited statistical correlations with residents' perceptions of safety. Those were types of communities, dwelling floor level, educational attainment, family size, and annual income. For predicting residents' perceptions of safety in their apartment territory, multiple regression models were obtained and residents' neighborhood attachment was also considered in the multiple regression models. The apartment community managers emphasized direct maintenance issues and residents' social contact with neighbors for improving residents' perceived safety. In conclusion, design and managerial suggestions for safer communities were proposed. For creating safer multi-family housing communities, territoriality and related architectural conditions and managerial considerations and residents' participations are emphasized. The concept of community programming for safer multi-family housing communities is suggested.

Sources of methane in China: A program to estimate emissions from rice paddy fields, bio-gas pits, and urban areas: Annual progress report  

DOE Green Energy (OSTI)

We are measuring methane from rice paddy fields and bio-gas pits. The project has produced new results that we are using to sharply focus the present study. We measured ambient concentrations at Minqin, Beijing, and Chendu. We obtained flux measurements from bio-gas pits, and flux measurements from rice paddy fields. Minqin is a background site with no large local sources of methane such as rice fields or urban areas. It serves as control for the experiment. Beijing is representative of a large industrialized Chinese city not affected by rice agriculture but heavily dependent on burning coal for cooking and heating. Chendu is in the heart of the rice producing areas of China where rice paddies cover millions of acres and methane from bio-gas pits is an important source of energy. Further progress was impeded by a lack of a formal agreement between the US and PRC, which was not signed until August 1987. 9 figs.

Identification of limiting case between DBA and SBDBA (CL break area sensitivity): A new model for the boron injection system  

SciTech Connect

Atucha-2 is a Siemens-designed PHWR reactor under construction in the Republic of Argentina. Its geometrical complexity and (e.g., oblique Control Rods, Positive Void coefficient) required a developed and validated complex three dimensional (3D) neutron kinetics (NK) coupled thermal hydraulic (TH) model. Reactor shut-down is obtained by oblique CRs and, during accidental conditions, by an emergency shut-down system (JDJ) injecting a highly concentrated boron solution (boron clouds) in the moderator tank, the boron clouds reconstruction is obtained using a CFD (CFX) code calculation. A complete LBLOCA calculation implies the application of the RELAP5-3D{sup C} system code. Within the framework of the third Agreement 'NA-SA - Univ. of Pisa' a new RELAP5-3D control system for the boron injection system was developed and implemented in the validated coupled RELAP5-3D/NESTLE model of the Atucha 2 NPP. The aim of this activity is to find out the limiting case (maximum break area size) for the Peak Cladding Temperature for LOCAs under fixed boundary conditions. (authors)

Testing a Coupled Global-limited-area Data Assimilation System Using Observations from the 2004 Pacific Typhoon Season  

E-Print Network (OSTI)

Tropical cyclone (TC) track and intensity forecasts have improved in recent years due to increased model resolution, improved data assimilation, and the rapid increase in the number of routinely assimilated observations over oceans. The data assimilation approach that has received the most attention in recent years is Ensemble Kalman Filtering (EnKF). The most attractive feature of the EnKF is that it uses a fully flow-dependent estimate of the error statistics, which can have important benefits for the analysis of rapidly developing TCs. We implement the Local Ensemble Transform Kalman Filter algorithm, a variation of the EnKF, on a reduced-resolution version of the National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) model and the NCEP Regional Spectral Model (RSM) to build a coupled global-limited area analysis/forecast system. This is the first time, to our knowledge, that such a system is used for the analysis and forecast of tropical cyclones. We use data from summer 2004 to study eight tropical cyclones in the Northwest Pacific. The benchmark data sets that we use to assess the performance of our system are the NCEP Reanalysis and the NCEP Operational GFS analyses from 2004. These benchmark analyses were both obtained by the Statistical Spectral Interpolation, which was the operational data assimilation system of NCEP in 2004. The GFS Operational analysis assimilated a large number of satellite radiance observations in addition to the observations assimilated in our system. All analyses are verified against the Joint Typhoon Warning Center Best Track data set. The errors are calculated for the position and intensity of the TCs. The global component of the ensemble-based system shows improvement in position analysis over the NCEP Reanalysis, but shows no significant difference from the NCEP operational analysis for most of the storm tracks. The regional component of our system improves position analysis over all the global analyses. The intensity analyses, measured by the minimum sea level pressure, are of similar quality in all of the analyses. Regional deterministic forecasts started from our analyses are generally not significantly different from those started from the GFS operational analysis. On average, the regional experiments performed better for longer than 48 h sea level pressure forecasts, while the global forecast performed better in predicting the position for longer than 48 h.

Towards sustainable urban communities  

Science Conference Proceedings (OSTI)

Requirements for the assessment tools of buildings have increased, assessing of building components or separate buildings is not enough. Neighbourhoods, built environment, public transportations, and services, should be considered simultaneously. Number of population living in urban areas is high and increasing rapidly. Urbanisation is a major concern due to its detrimental effects on the environment. The aim of this study is to clarify the field of assessment tools for urban communities by analysing the current situation. The focus is on internationally well known assessment tools; BREEAM Communities, CASBEE for Urban Development and LEED for Neigborhood Development. The interest towards certification systems is increasing amongst the authorities, and especially amongst the global investors and property developers. Achieved certifications are expected to bring measureable publicity for the developers. The assessment of urban areas enables the comparison of municipalities and urban areas, and notably supports decision making processes. Authorities, city planners, and designers would benefit most from the use of the tools during the decision making process. - Highlights: Black-Right-Pointing-Pointer The urban assessment tools have strong linkage to the region. Black-Right-Pointing-Pointer The tools promote complementary building and retrofitting existing sites. Black-Right-Pointing-Pointer Sharing knowledge and experiences is important in the development of the tools.

A proposed calculational model for two-phase countercurrent flow limitation in channels with abrupt area charge  

Science Conference Proceedings (OSTI)

A model to calculate the void fraction in counter-current flow for geometries with abrupt area change is proposed. Continuity and momentum equations are used to derive a quartic equation for the void fraction. By varying the known physical parameters, the quartic equation is solved to get a wide range of results that are physically consistent. The model is applied for the special case of flooding at abrupt area change geometry, and a comparison with data is made.

Higher U.S. Crop Prices Trigger Little Area Expansion so Marginal Land for Biofuel Crops Is Limited  

SciTech Connect

By expanding energy biomass production on marginal lands that are not currently used for crops, food price increases and indirect climate change effects can be mitigated. Studies of the availability of marginal lands for dedicated bioenergy crops have focused on biophysical land traits, ignoring the human role in decisions to convert marginal land to bioenergy crops. Recent history offers insights about farmer willingness to put non-crop land into crop production. The 2006-09 leap in field crop prices and the attendant 64% gain in typical profitability led to only a 2% increase in crop planted area, mostly in the prairie states

Authorized Limits for the Release of a 25 Ton Locomotive, Serial Number 21547, at the Area 25 Engine Maintenance, Assembly, and Disassembly Facility, Nevada Test Site, Nevada  

SciTech Connect

This document contains process knowledge and radiological data and analysis to support approval for release of the 25-ton locomotive, Serial Number 21547, at the Area 25 Engine Maintenance, Assembly, and Disassembly (EMAD) Facility, located on the Nevada Test Site (NTS). The 25-ton locomotive is a small, one-of-a-kind locomotive used to move railcars in support of the Nuclear Engine for Rocket Vehicle Application project. This locomotive was identified as having significant historical value by the Nevada State Railroad Museum in Boulder City, Nevada, where it will be used as a display piece. A substantial effort to characterize the radiological conditions of the locomotive was undertaken by the NTS Management and Operations Contractor, National Security Technologies, LLC (NSTec). During this characterization process, seven small areas on the locomotive had contamination levels that exceeded the NTS release criteria (limits consistent with U.S. Department of Energy [DOE] Order DOE O 5400.5, “Radiation Protection of the Public and the Environment”). The decision was made to perform radiological decontamination of these known accessible impacted areas to further the release process. On February 9, 2010, NSTec personnel completed decontamination of these seven areas to within the NTS release criteria. Although all accessible areas of the locomotive had been successfully decontaminated to within NTS release criteria, it was plausible that inaccessible areas of the locomotive (i.e., those areas on the locomotive where it was not possible to perform radiological surveys) could potentially have contamination above unrestricted release limits. To access the majority of these inaccessible areas, the locomotive would have to be disassembled. A complete disassembly for a full radiological survey could have permanently destroyed parts and would have ruined the historical value of the locomotive. Complete disassembly would also add an unreasonable financial burden for the contractor. A decision was reached between the NTS regulator and NSTec, opting for alternative authorized limits from DOE Headquarters. In doing so, NSTec personnel performed a dose model using the DOE-approved modeling code RESRAD-BUILD v3.5 to evaluate scenarios. The parameters used in the dose model were conservative. NSTec’s Radiological Engineering Calculation, REC-2010-001, “Public Dose Estimate from the EMAD 25 Ton Locomotive,” concluded that the four scenarios evaluated were below the 25-millirem per year limit, the “likely” dose scenarios met the “few millirem in a year” criteria, and that the EMAD 25-ton locomotive met the radiological requirements to be released with residual radioactivity to the public.

Approach to Recover Hydrocarbons from Currently Off-Limit Areas of the Antrim Formation, MI Using Low-Impact Technologies  

SciTech Connect

The goal of this project was to develop and execute a novel drilling and completion program in the Antrim Shale near the western shoreline of Northern Michigan. The target was the gas in the Lower Antrim Formation (Upper Devonian). Another goal was to see if drilling permits could be obtained from the Michigan DNR that would allow exploitation of reserves currently off-limits to exploration. This project met both of these goals: the DNR (Michigan Department of Natural Resources) issued permits that allow drilling the shallow subsurface for exploration and production. This project obtained drilling permits for the original demonstration well AG-A-MING 4-12 HD (API: 21-009-58153-0000) and AG-A-MING 4-12 HD1 (API: 21-009-58153-0100) as well as for similar Antrim wells in Benzie County, MI, the Colfax 3-28 HD and nearby Colfax 2-28 HD which were substituted for the AG-A-MING well. This project also developed successful techniques and strategies for producing the shallow gas. In addition to the project demonstration well over 20 wells have been drilled to date into the shallow Antrim as a result of this project's findings. Further, fracture stimulation has proven to be a vital step in improving the deliverability of wells to deem them commercial. Our initial plan was very simple; the 'J-well' design. We proposed to drill a vertical or slant well 30.48 meters (100 feet) below the glacial drift, set required casing, then angle back up to tap the resource lying between the base to the drift and the conventional vertical well. The 'J'-well design was tested at Mancelona Township in Antrim County in February of 2007 with the St. Mancelona 2-12 HD 3.

Urban and Regional Air Quality  

NLE Websites -- All DOE Office Websites (Extended Search)

equipment equipment Urban and Regional Air Quality Research in this area is concerned with regional air quality issues such as: Controlling nitrogen oxides (NOx) and volatile organic compounds, to manage tropospheric ozone pollution. Hazardous air pollutants: using science to base standards on rigorously studied risks. Air quality and climate: how does climate influence air quality at a regional or local level? Current modeling practices often do not capture variations in pollutants such as ozone-they represent a limited sample of the diverse meteorology and human behavior that affect air pollution. Improved modeling of regional air quality will help understand variability, reveal patterns of behavior, and pollutant transport issues. Controlled experiments in lab and field can help validate improved models.

Hopping robots provide the possibility of breaking the link between the size of a ground vehicle and the largest obstacle that it can overcome. For more than a decade, DARPA and Sandia National Laboratories have been developing small-scale hopping robot technology, first as part of purely hopping platforms and, more recently, as part of platforms that are capable of both wheeled and hopping locomotion. In this paper we introduce the Urban Hopper robot and summarize its capabilities. The advantages of hopping for overcoming certain obstacles are discussed. Several configurations of the Urban Hopper are described, as are intelligent capabilities of the system. Key challenges are discussed.

Transportation of radionuclides in urban environs: draft environmental assessment  

Science Conference Proceedings (OSTI)

This report assesses the environmental consequences of the transportation of radioactive materials in densely populated urban areas, including estimates of the radiological, nonradiological, and social impacts arising from this process. The chapters of the report and the appendices which follow detail the methodology and results for each of four causative event categories: incident free transport, vehicular accidents, human errors or deviations from accepted quality assurance practices, and sabotage or malevolent acts. The numerical results are expressed in terms of the expected radiological and economic impacts from each. Following these discussions, alternatives to the current transport practice are considered. Then, the detailed analysis is extended from a limited area of New York city to other urban areas. The appendices contain the data bases and specific models used to evaluate these impacts, as well as discussions of chemical toxicity and the social impacts of radioactive material transport in urban areas. The latter are evaluated for each causative event category in terms of psychological, sociological, political, legal, and organizational impacts. The report is followed by an extensive bibliography covering the many fields of study which were required in performing the analysis.

Analysis of large urban fires  

SciTech Connect

Fires in urban areas caused by a nuclear burst are analyzed as a first step towards determining their smoke-generation chacteristics, which may have grave implications for global-scale climatic consequences. A chain of events and their component processes which would follow a nuclear attack are described. A numerical code is currently being developed to calculate ultimately the smoke production rate for a given attack scenario. Available models for most of the processes are incorporated into the code. Sample calculations of urban fire-development history performed in the code for an idealized uniform city are presented. Preliminary results indicate the importance of the wind, thermal radiation transmission, fuel distributions, and ignition thresholds on the urban fire spread characteristics. Future plans are to improve the existing models and develop new ones to characterize smoke production from large urban fires. 21 references, 18 figures.

Turbulent Kinetic Energy in the Oklahoma City Urban Environment  

DOE Green Energy (OSTI)

A major field experiment, Joint URBAN 2003 (JU2003), was conducted in Oklahoma City in July 2003 to collect meteorological and tracer data sets for evaluating dispersion models in urban areas. The Department of Homeland Security and the Defense Threat Reduction Agency were the primary sponsors of JU2003. Investigators from five Department of Energy national laboratories, several other government agencies, universities, private companies, and international agencies conducted the experiment. Observations to characterize the meteorology in and around the urban area complemented the observation of the dispersion of SF6, an inert tracer gas. Over one hundred threedimensional sonic anemometers were deployed in and around the urban area to monitor wind speed, direction, and turbulence fluxes during releases of SF6. Sonic deployment locations included a profile of eight sonic anemometers mounted on a crane less than 1 km north of the central business district (CBD). Using data from these and other sonic anemometers deployed in the urban area, we can quantify the effect of the urban area on atmospheric turbulence and compare results seen in OKC to those in other urban areas to assess the parameters typically used in parameterizations of urban turbulence.

Simple laws of urban growth  

E-Print Network (OSTI)

By analysing the evolution of the street network of Greater London from the late 1700s to the present, we are able to shed light on the inner mechanisms that lie behind the growth of a city. First we define an object called a city as a spatial discontinuous phenomena, from clustering the density of street intersections. Second, we find that the city growth mechanisms can be described by two logistic laws, hence can be determined by a simple model of urban network growth in the presence of competition for limited space.

Swarm Intelligence for Urban Dynamics Modelling  

Science Conference Proceedings (OSTI)

In this paper, we propose swarm intelligence algorithms to deal with dynamical and spatial organization emergence. The goal is to model and simulate the developement of spatial centers using multi-criteria. We combine a decentralized approach based on emergent clustering mixed with spatial constraints or attractions. We propose an extension of the ant nest building algorithm with multi-center and adaptive process. Typically, this model is suitable to analyse and simulate urban dynamics like gentrification or the dynamics of the cultural equipment in urban area.

Spatial Analysis of Residential Development and Urban-Rural Zoning in Baltimore County, Maryland  

E-Print Network (OSTI)

Over the past half-century, Baltimore County, Maryland has experienced various policy measures that have shaped development patterns. This thesis analyzes three spatially explicit parcel-level models of residential development in Baltimore County to examine the effects of land-use regulations on multiple density classes from 1996 to 2008. The first model analyzes the entire county, while the second analyzes areas outside the county urban growth boundary, while the third model studied areas inside the boundary. While this region has been previously analyzed, prior studies have generally ignored policy affects upon the density of new residential subdivisions. The use of a binary dependent variable, i.e. develop or not develop, represents a critical oversight as this assumes policy measures exert a uniform impact across all development types. This study addressed this issue with the literature by using a multinomial logit model to differentiate the effects of various development policies to better understand residential growth. The objective of this research is to determine what factors influence individual landowner's decision to convert an undeveloped property to residential use. The impacts of rural conservation (RC) zoning and urban growth boundaries (UGB) comprise the prominent land-use regulations analyzed in this study. The empirical estimates provided significant evidence that maximum density zoning effectively limits the density of new residential development in almost every model. Other policy measures, mainly rural legacy areas and critical areas, were generally found to be ineffective at limiting growth. This research concludes that maximum density zoning comprises the strongest tool for limiting development to a density mandated by the county government. Finally, maps depicting the predicted probability of development at two densities are included and discussed to indicate the areas most likely to be subdivided for residential land use.

Global Cooling: Effect of Urban Albedo on Global Temperature  

SciTech Connect

In many urban areas, pavements and roofs constitute over 60% of urban surfaces (roof 20-25%, pavements about 40%). The roof and the pavement albedo can be increased by about 0.25 and 0.10, respectively, resulting in a net albedo increase for urban areas of about 0.1. Many studies have demonstrated building cooling-energy savings in excess of 20% upon raising roof reflectivity from an existing 10-20% to about 60%. We estimate U.S. potential savings in excess of $1 billion (B) per year in net annual energy bills. Increasing albedo of urban surfaces can reduce the summertime urban temperature and improve the urban air quality. Increasing the urban albedo has the added benefit of reflecting more of the incoming global solar radiation and countering the effect of global warming. We estimate that increasing albedo of urban areas by 0.1 results in an increase of 3 x 10{sup -4} in Earth albedo. Using a simple global model, the change in air temperature in lowest 1.8 km of the atmosphere is estimated at 0.01K. Modelers predict a warming of about 3K in the next 60 years (0.05K/year). Change of 0.1 in urban albedo will result in 0.01K global cooling, a delay of {approx}0.2 years in global warming. This 0.2 years delay in global warming is equivalent to 10 Gt reduction in CO2 emissions.

The Network Analysis of Urban Streets: A Primal Approach  

E-Print Network (OSTI)

The network metaphor in the analysis of urban and territorial cases has a long tradition especially in transportation/land-use planning and economic geography. More recently, urban design has brought its contribution by means of the "space syntax" methodology. All these approaches, though under different terms like accessibility, proximity, integration,connectivity, cost or effort, focus on the idea that some places (or streets) are more important than others because they are more central. The study of centrality in complex systems,however, originated in other scientific areas, namely in structural sociology, well before its use in urban studies; moreover, as a structural property of the system, centrality has never been extensively investigated metrically in geographic networks as it has been topologically in a wide range of other relational networks like social, biological or technological. After two previous works on some structural properties of the dual and primal graph representations of urban street ne...

OZONE PRODUCTION IN URBAN PLUMES.  

SciTech Connect

Ozone levels observed during a field campaign in Houston were significantly higher than that observed in Phoenix or Philadelphia. An examination of the slope of O{sub x} versus NO{sub z} in the urban plumes shows that NO{sub x} is used 2 to 3 times more efficiently in Houston as compared with Phoenix and Philadelphia. Representative values of OPEx are 7-12, 3, and 4, in Houston, Phoenix, and Philadelphia. Aircraft observations have been used to calculate P(O{sub 3})/P(NO{sub z}). Values in Houston are significantly higher than in Phoenix and Philadelphia. We show that P(O{sub 3})/P(NO{sub z}) is proportional to a VOC/NO{sub 2}-OH reactivity ratio. High values of P(O{sub 3})/P(NO{sub z}) in Houston are due to emissions of reactive olefins from the ship channel region. It is significant that high values of P(O{sub 3})/P(NO{sub z}) occur at NO{sub x} levels up to several 10's of ppb. Not only is the chemistry efficient but it will be long lasting. The occurrence of high NO{sub x} and high OPEx is fostered by the co-location of VOC and NO{sub x} sources in the Houston industrial areas.

Constructing a GIS-based 3D urban model using LiDAR and aerial photographs  

E-Print Network (OSTI)

Due to the increasing availability of high-resolution remotely sensed imagery and detailed terrain surface elevation models, urban planners and municipal managers can now model and visualize the urban space in three dimensions. The traditional approach to the representation of urban space is 2D planimetric maps with building footprints, facilities and road networks. Recently, a number of methods have been developed to represent true 3D urban models. Those include panoramic imaging, Virtual Reality Modeling Language (VRML), and Computer-aided Design (CAD). These methods focus on aesthetic representation, but they do not have sufficient spatial query and analytical capabilities. This research evaluates the conventional approaches to 3D urban models, and identifies their advantages and limitations; GIS functionalities have been combined with 3D urban visualization techniques to develop a GIS-based urban modeling method; The algorithms and techniques have been explored to derive urban objects and their attributes from airborne LiDAR and high-resolution imagery for constructing and visualizing 3D urban models; and 3D urban models for the Texas A&M University (TAMU) campus and downtown Houston have been implemented using the algorithms and techniques developed in this research. By adding close-range camera images and highresolution aerial photographs as the texture of urban objects, effect of photorealism visualization has been achieved for walk-through and fly-through animations. The Texas A&M University campus model and the downtown Houston model have been implemented to offer proof-of-concept, namely, to demonstrate the advantages of the GIS-based approach. These two prototype applications show that the GIS-based 3D urban modeling method, by coupling ArcGIS and MultiGen-Paradigm Site Builder 3D software, can realize the desired functionalities in georeferencing, geographical measurements, spatial query, spatial analysis, and numerical modeling in 3D visual environment.

Characterization of urban solid waste in Chihuahua, Mexico  

Science Conference Proceedings (OSTI)

The characterization of urban solid waste generation is fundamental for adequate decision making in the management strategy of urban solid waste in a city. The objective of this study is to characterize the waste generated in the households of Chihuahua city, and to compare the results obtained in areas of the city with three different socioeconomic levels. In order to identify the different socioeconomic trends in waste generation and characterization, 560 samples of solid waste were collected during 1 week from 80 households in Chihuahua and were hand sorted and classified into 15 weighted fractions. The average waste generation in Chihuahua calculated in this study was 0.676 kg per capita per day in April 2006. The main fractions were: organic (48%), paper (16%) and plastic (12%). Results show an increased waste generation associated with the socioeconomic level. The characterization in amount and composition of urban waste is the first step needed for the successful implementation of an integral waste management system.

A new energy code for residential buildings in Israel defines a required level of solar insolation of the buildings according to different city areas, orientations and climatic zones. These requirements were used to define objective criteria for solar rights regulations. Following, we define a method and a simple design tool that allows achieving the required solar insolation. Three methods were suggested; two are based on performance approach while

Nuclear EMP simulation for large-scale urban environments. FDTD for electrically large problems.  

SciTech Connect

In case of a terrorist nuclear attack in a metropolitan area, EMP measurement could provide: (1) a prompt confirmation of the nature of the explosion (chemical or nuclear) for emergency response; and (2) and characterization parameters of the device (reaction history, yield) for technical forensics. However, urban environment could affect the fidelity of the prompt EMP measurement (as well as all other types of prompt measurement): (1) Nuclear EMP wavefront would no longer be coherent, due to incoherent production, attenuation, and propagation of gamma and electrons; and (2) EMP propagation from source region outward would undergo complicated transmission, reflection, and diffraction processes. EMP simulation for electrically-large urban environment: (1) Coupled MCNP/FDTD (Finite-difference time domain Maxwell solver) approach; and (2) FDTD tends to be limited to problems that are not 'too' large compared to the wavelengths of interest because of numerical dispersion and anisotropy. We use a higher-order low-dispersion, isotropic FDTD algorithm for EMP propagation.

Dispersal and fallout simulations for urban consequences management (u)  

SciTech Connect

Hazardous chemical, biological, or radioactive releases from leaks, spills, fires, or blasts, may occur (intentionally or accidentally) in urban environments during warfare or as part of terrorist attacks on military bases or other facilities. The associated contaminant dispersion is complex and semi-chaotic. Urban predictive simulation capabilities can have direct impact in many threat-reduction areas of interest, including, urban sensor placement and threat analysis, contaminant transport (CT) effects on surrounding civilian population (dosages, evacuation, shelter-in-place), education and training of rescue teams and services. Detailed simulations for the various processes involved are in principle possible, but generally not fast. Predicting urban airflow accompanied by CT presents extremely challenging requirements. Crucial technical issues include, simulating turbulent fluid and particulate transport, initial and boundary condition modeling incorporating a consistent stratified urban boundary layer with realistic wind fluctuations, and post-processing of the simulation results for practical consequences management. Relevant fluid dynamic processes to be simulated include, detailed energetic and contaminant sources, complex building vortex shedding and flows in recirculation zones, and modeling of particle distributions, including particulate fallout, as well as deposition, re-suspension and evaporation. Other issues include, modeling building damage effects due to eventual blasts, addressing appropriate regional and atmospheric data reduction.

Urban household energy use in Thailand  

SciTech Connect

Changes in household fuel and electricity use that accompany urbanization in Third World countries bear large economic and environmental costs. The processes driving the fuel transition, and the policy mechanisms by which it can be influenced, need to be better understood for the sake of forecasting and planning, especially in the case of electricity demand. This study examines patterns of household fuel use and electrical appliance utilization in Bangkok, Chieng Mai and Ayutthaya, Thailand, based on the results of a household energy survey. Survey data are statistically analyzed using a variety of multiple regression techniques to evaluate the relative influence of various household and fuel characteristics on fuel and appliance choice. Results suggest that changes to the value of women's time in urban households, as women become increasingly active in the labor force, have a major influence on patterns of household energy use. The use of the home for small-scale commercial activities, particularly food preparation, also has a significant influence on fuel choice. In general, household income does not prove to be an important factor in fuel and appliance selection in these cities, although income is closely related to total electricity use. The electricity use of individual household appliances is also analyzed using statistical techniques as well as limited direct metering. The technology of appliance production in Thailand is evaluated through interviews with manufacturers and comparisons of product performance. These data are used to develop policy recommendations for improving the efficiency of electrical appliances in Thailand by relying principally on the dynamism of the consumer goods market, rather than direct regulation. The annual electricity savings from the recommended program for fostering rapid adoption of efficient technologies are estimated to reach 1800 GWh by the year 2005 for urban households alone.

Water Conservation with Urban Landscape Plants  

E-Print Network (OSTI)

Water shortages are a common problem in much of the southwest. Increasing urbanization and increasing population places greater demands on dwindling water supplies. Over half of the water used in urban areas of the southwest is used in the irrigation of landscapes. To help cope with increased urban water demands and low water supplies, research was conducted from March 1981 to July 1983 at The Texas Agricultural Experiment Station at Dallas to gain information relative to consumptive water use by native and non-native landscape plants. Twenty weighing lysimeters were constructed and installed and plants established in the lysimeters and adjacent areas. The lysimeters were made from 0.6 X 0.9 m undisturbed cores of Austin silty clay soil. Plants used in the lysimeter study were buffalograss, St. Augustine grass, cenizo, boxwood and Texas barberry. All plants are native to Texas except boxwood and St. Augustine grass. Four lysimeters were planted to each plant type. This allowed two moisture levels and two replications of each plant type. There was no difference in water use by St. Augustine grass and buffalo grass during the year of establishment. Daily water use ranged from 0.49 to 0.08 cm per day but was generally 50% class A pan evaporation. St. Augustine grass used 0.03 cm/day more water than buffalo grass during 1982. -Irrigation treatments used in 1982 did not influence water use by either grass type but buffalo grass retained higher quality under dry treatment (irrigated at 0.40 bar moisture tension) than St. Augustine grass. Water use from May to July 1983 was highest (of all treatments) by St. Augustine grass when irrigated at 0.25 bar soil moisture tension at 76 cm depth and lowest (of all treatments) by buffalograss when irrigated at 0.75 bar soil moisture tension at 76 cm depth. Application of 50% class A pan evaporation each week appears to be an acceptable guideline for irrigation of either turfgrass but research should be conducted over a longer time period to obtain more specific guidelines for each grass species. Water use by shrubs in lysimeters was variable and not influenced by plant type during the period of establishment (Fall 1981). During 1982 water use was influenced more by plant size than by specie or water level. Cenizo had much faster growth rate than the other shrubs in the study. Water use by container grown plants indicated that cenizo had higher water use efficiency than boxwood or Indian Hawthorn. Water use was determined for several native shrubs and of the ones compared, Texas barberry appeared to have the most promise for use in water conserving landscapes.

Energy in the urban environment: the role of energy use and energy efficiency in buildings  

SciTech Connect

A century ago, the world had many cities of which the greatest were magnificent centers of culture and commerce. However, even in the most industrialized countries at the time, only a tiny fraction of the people lived in these cities. Most people lived in rural areas, in small towns, in villages, and on farms. Visits to a great city were, for most of the population, uncommon events often of great fascination. The world has changed dramatically in the intervening years. Now most of the industrial world lives in urban areas in close proximity to large cities. Industry is often located in these vast urban areas. As the urbanized zones grow in extent, they begin to approach one another, as on the East Coast of the United States. The phenomenon of urbanization has moved to developing countries as well. There has been a flood of migrants who have left impoverished rural areas to seek economic opportunities in urban areas throughout the developing world. This movement from the countryside to cities has changed the entire landscape and economies of developing nations. Importantly, the growth of cities places very great demands on infrastructure. Transportation systems are needed to assure that a concentrated population can receive food from the countryside without fail. They are needed to assure personal and work-related travel. Water supplies must be created, water must be purified and maintained pure, and this water must be made available to a large population. Medical services--and a host of other vital services--must be provided to the population. Energy is a vital underpinning of all these activities, and must be supplied to the city in large quantities. Energy is, in many ways, the enabler of all the other services on which the maintenance of urban life depends. In this paper, we will discuss the evolution of energy use in residential and commercial buildings. This topic goes beyond urban energy use, as buildings exist in both urban and non-urban areas. The topic does not address all energy use in cities--urban transportation is clearly important. However, buildings are the largest energy consumer in cities by a wide margin. (A typical Western home will consume at least five times as much energy as the typical car that services it.) As we note later, buildings consume more than one-third of total commercial energy globally. In developing countries, a large portion of energy use in buildings is in urban areas even though there are still large populations in rural areas. This is because vast quantities of non-commercial energy--residue from plants, farm products, forests and dung from animals--are used to provide the services needed in households (primarily cooking and water heating) in many rural areas. Most of industrial energy use (which accounts for slightly more than 40 percent of global energy use) is outside of urban areas. Thus, any effort to address energy use in urban areas needs necessarily to deal with the energy use in buildings.

Adaptive Urban Dispersion Integrated Model  

DOE Green Energy (OSTI)

Numerical simulations represent a unique predictive tool for understanding the three-dimensional flow fields and associated concentration distributions from contaminant releases in complex urban settings (Britter and Hanna 2003). Utilization of the most accurate urban models, based on fully three-dimensional computational fluid dynamics (CFD) that solve the Navier-Stokes equations with incorporated turbulence models, presents many challenges. We address two in this work; first, a fast but accurate way to incorporate the complex urban terrain, buildings, and other structures to enforce proper boundary conditions in the flow solution; second, ways to achieve a level of computational efficiency that allows the models to be run in an automated fashion such that they may be used for emergency response and event reconstruction applications. We have developed a new integrated urban dispersion modeling capability based on FEM3MP (Gresho and Chan 1998, Chan and Stevens 2000), a CFD model from Lawrence Livermore National Lab. The integrated capability incorporates fast embedded boundary mesh generation for geometrically complex problems and full three-dimensional Cartesian adaptive mesh refinement (AMR). Parallel AMR and embedded boundary gridding support are provided through the SAMRAI library (Wissink et al. 2001, Hornung and Kohn 2002). Embedded boundary mesh generation has been demonstrated to be an automatic, fast, and efficient approach for problem setup. It has been used for a variety of geometrically complex applications, including urban applications (Pullen et al. 2005). The key technology we introduce in this work is the application of AMR, which allows the application of high-resolution modeling to certain important features, such as individual buildings and high-resolution terrain (including important vegetative and land-use features). It also allows the urban scale model to be readily interfaced with coarser resolution meso or regional scale models. This talk will discuss details of the approach and present results for some example calculations performed in Manhattan in support of the DHS Urban Dispersion Program (UDP) using some of the tools developed as part of this new capability.

Global Cooling: Increasing World-Wide Urban Albedos to Offset CO2  

Science Conference Proceedings (OSTI)

Modification of urban albedos reduces summertime urban temperatures, resulting in a better urban air quality and building air-conditioning savings. Furthermore, increasing urban albedos has the added benefit of reflecting some of the incoming global solar radiation and countering to some extent the effects of global warming. In many urban areas, pavements and roofs constitute over 60% of urban surfaces (roof 20-25%, pavements about 40%). Using reflective materials, both roof and the pavement albedos can be increased by about 0.25 and 0.10, respectively, resulting in a net albedo increase for urban areas of about 0.1. Many studies have demonstrated building cooling-energy savings in excess of 20% upon raising roof reflectivity from an existing 10-20% to about 60% (a U.S. potential savings in excess of $1 billion (B) per year in net annual energy bills). On a global basis, our preliminary estimate is that increasing the world-wide albedos of urban roofs and paved surfaces will induce a negative radiative forcing on the earth equivalent to removing {approx} 22-40 Gt of CO{sub 2} from the atmosphere. Since, 55% of the emitted CO{sub 2} remains in the atmosphere, removal of 22-40 Gt of CO{sub 2} from the atmosphere is equivalent to reducing global CO{sub 2} emissions by 40-73 Gt. At {approx} $25/tonne of CO{sub 2}, a 40-73 Gt CO{sub 2} emission reduction from changing the albedo of roofs and paved surfaces is worth about $1,000B to 1800B. These estimated savings are dependent on assumptions used in this study, but nevertheless demonstrate considerable benefits that may be obtained from cooler roofs and pavements.

Detector limitations, STAR  

Science Conference Proceedings (OSTI)

Every detector has limitations in terms of solid angle, particular technologies chosen, cracks due to mechanical structure, etc. If all of the presently planned parts of STAR [Solenoidal Tracker At RHIC] were in place, these factors would not seriously limit our ability to exploit the spin physics possible in RHIC. What is of greater concern at the moment is the construction schedule for components such as the Electromagnetic Calorimeters, and the limited funding for various levels of triggers.

Interaction of Nocturnal Low-Level Jets with Urban Geometries as seen in Joint URBAN 2003 Data  

DOE Green Energy (OSTI)

The nocturnal low-level jet (LLJ) is a well-documented phenomenon world-wide, especially in the southern Great Plains of the United States (Bonner 1968, Whiteman et al. 1997, Banta et al., 2002) where it contributes to severe weather. In the canonical rural case, the nocturnal LLJ forms as the release of daytime convective turbulent stresses allow nighttime winds above a stable boundary layer to accelerate to supergeostrophic wind speeds. In situations with surface winds of less than 5 m/s, wind speeds at altitudes of 100m due to the nocturnal LLJ can be greater than 20 m/s. The turbulence generated by this wind shear can induce nocturnal mixing events and control surface-atmosphere exchange, thereby affecting atmospheric transport and dispersion. The Joint URBAN 2003 urban dispersion dataset, collected in Oklahoma City in July, 2003, includes several occurrences of strong LLJs, thereby providing a unique opportunity to document how the LLJ interacts with the complexity of urban geometries and to explore the significance of LLJs for transport and dispersion in urban environments. Based on this dataset, we will answer the following questions: (1) How often do LLJs occur during the experiment? (2) How does the increase in surface roughness represented by the city center, as compared to the rural environment, affect the altitude and speed of the jet, based on data from upwind and downwind wind profiles? (3) How often do LLJs contribute to nocturnal mixing events within the Oklahoma City urban area, as observed in profiles of turbulence quantities at an 80m pseudo-tower located 750m downwind of Oklahoma City center? (4) Can the effect of these LLJ-induced mixing events be identified in the dispersion datasets?

LES based urban dispersal predictions for consequence management  

Science Conference Proceedings (OSTI)

It is unlikely that we will ever have a deterministic predictive framework for the study of flows in urban scale scenarios purely based on computational fluid dynamics. This is due to the inherent difficulty in modeling and validating all relevant physical sub-processes and acquiring all the necessary and relevant boundary condition information. On the other hand, this case is representative of very fundamental ones for which whole-domain scalable laboratory (or field) studies are impossible or very difficult, but for which it is also crucial to develop predictability. In this paper, we discuss a framework for detailed dispersal predictions in urban and regional settings based on effective linkage of strong motion codes - capable of simulating detailed energetic and contaminant sources, and large-eddy simulation - capable of emulating contaminant transport due to wind and turbulence fields in built-up areas. Challenging technical aspects of the simulation approach are outlined and recent progress is reviewed in th is context.

Urban alternative homestead  

DOE Green Energy (OSTI)

The three main areas of work were in redesigning and correcting the design flaws of the active heating system, the passive solar heating system, and the furnace controls, so that the building would heat and cool itself more efficiently and evenly than it had before. The active system was re-plumbed, fixing leaks, and adding joints and parts needed to work properly. Its tanks were insulated and new pumps installed. The passive system was reworked by adding a shadescreen to the outside of the greenhouse for summer cooling, and by adding ductwork to remove excess heat from the greenhouse and office, and redistribute it to the rest of the building, or to the outside. To help heat the north rooms, this recycled heat was very helpful. Also, insulating the floor under the north rooms was very helpful in providing more even heating. In order for the heating system to operate more efficiently, the electronic controls had to be reworked so the proper messages could be sent to the furnace about when to use each kind of heat. The lowered gas usage of the house told the story about how much better the active and passive systems were when the grant was completed. Moreover, the house was much more comfortable, not only from the overheating in the summer, but from a more even distribution of the heat to the north rooms. The fact that the electrical usage increased reflected the fact that the new pumps took more electricity to run them, and that the active system did not have all of the flaws worked out.

A Study of the Effects of Different Urban Wind Models on Dispersion Patterns Using Joint Urban 2003 Data  

SciTech Connect

The Quick Urban & Industrial Complex (QUIC) Dispersion Modeling System has been developed to rapidly compute the transport and dispersion of toxic agent releases in the vicinity of buildings. It is composed of a wind solver, an 'urbanized' Lagrangian random-walk model, and a graphical user interface. QUIC has two different wind models: (a) The QUIC-URB wind solver, an empirically-based diagnostic wind model and (b) The QUIC-CFD (RANS) solver, based on the 3D Reynolds-Averaged Navier-Stokes (RANS) equations. In this paper, we discuss the effect of different wind models on dispersion patterns in dense built-up areas. The model-computed wind from the two urban wind models- QUIC-URB and QUIC-CFD are used to drive the dispersion model. The concentration fields are then compared to measurements from the Oklahoma City Joint Urban 2003 field experiment. QUIC produces high-resolution 3-D mean wind and concentration fields around buildings, in addition to deposition on the ground and building surfaces. It has options for different release types, including point, moving point, line, area, and volumetric sources, as well as dense gas, explosive buoyant rise, multi-particle size, bioslurry, and two-phase releases. Other features include indoor infiltration, a pressure solver, outer grid simulations, vegetative canopies, and population exposure calculations. It has been used for biological agent sensor siting in cities, vulnerability assessments for heavier-than-air chemical releases at industrial facilities, and clean-up assessments for radiological dispersal device (RDD) releases in cities (e.g., see Linger et al., 2005; Brown, 2006a, b). QUIC has also been used for dust transport studies (Bowker et al., 2007a) and for the impact of highway sound barriers on the transport and dispersion of vehicle emissions (Bowker et al., 2007b).

An assessment of management practices of wood and wood-related wastes in the urban environment  

DOE Green Energy (OSTI)

The US Environmental Protection Agency estimates that yard waste{sup 1} accounts for approximately 16% of the municipal solid waste (MSW) stream (US EPA, 1994). Until recently, specific data and related information on this component of the (MSW) stream has been limited. The purposes of this study, phase two of the three-phase assessment of urban wood waste issues, are to assess and describe current alternatives to landfills for urban wood waste management; provide guidance on the management of urban wood waste to organizations that produce or manage wood waste; and clarify state regulatory and policy positions affecting these organizations. For this study, urban wood waste is defined as solid waste generated by tree and landscape maintenance services (public and private). Urban wood waste includes the following materials: unchipped mixed wood, unchipped logs, and unchipped tops and brush; clearing and grubbing waste; fall leaves and grass clippings; and chips and whole stumps. Construction and demolition debris and consumer-generated yard waste are not included in this study. Generators of urban wood waste include various organizations; municipal, county, and commercial tree care divisions; nurseries, orchards, and golf courses; municipal park and recreation departments; and electric and telephone utility power line maintenance, excavator and land clearance, and landscape organizations. (1) US EPA defines yard waste as ''yard trimmings'' which includes ''grass, leaves and tree brush trimmings from residential, institutional, and commercial sources.''

Shaping urban form without zoning: a case study of houston  

E-Print Network (OSTI)

Houston is the only major city in North America without zoning. The growth of Houston illustrates a traditional free market philosophy in which land use zoning is seen as a violation to private property and personal liberty. This dissertation explores how the lack of zoning has an impact on land use and urban form in Houston. It is based on a theoretical framework derived from economics and public policy theories for institutional analyses of land development controls. The dissertation uses cluster analysis integrating socioeconomic factors from census data to select three case study neighborhoods, and then applies GIS to analyze their urban form spatial characteristics with spatial data from Houston Planning Department. It also uses qualitative methods such as archives and documentations for the three neighborhoods. The study investigates the change of urban form in three case study neighborhoods over two decades. It also explores how local land use policies made by both the local government and non-governmental sectors shape urban form in Houston. The study results show that despite the city’s lack of zoning, local land use regulatory policies made by the municipality have significant influence on urban development. Additionally, civic and private organizations such as super neighborhoods and homeowner associations fill the gaps left by the lack of land use zoning. These two aspects contribute to land use planning and urban form of the city. Houston presents a contradiction of limited government intervention and public investments and subsidies. Land use controls by private contract and by government legislative intervention are not mutually exclusive or immutable. The study finds that it is difficult to achieve mixed race and income neighborhoods, even without zoning. Equity goals are not met in market approaches. Deed restrictions might be better at facilitating property sales and maintenance than at improving community welfare and governance. From the theoretical perspective, the study argues that a spectrum of market solutions and planning approaches at the ends are more relevant than the bipolarity view. Equity goals are not met in market approaches. For welfare and rights, public planning intervention is necessary. The market might provide physical land use diversity, but it fails to support socioeconomic diversity.

The Transportation Energy and Carbon Footprints of the 100 Largest U.S. Metropolitan Areas  

Science Conference Proceedings (OSTI)

We present estimates of the automobile and truck travel based energy and carbon footprints of the largest 100 U.S. metropolitan areas. The footprints are based on the estimated vehicle miles traveled and the transportation fuels consumed. Results are presented on an annual basis and represent end use emissions only. Total carbon emissions, emissions per capita, and emissions per dollar of gross metropolitan product are reported. Two years of annual data were examined, 2000 and 2005, with most of the in-depth analysis focused on the 2005 results. In section 2 we provide background data on the national picture and derive some carbon and energy consumption figures for the nation as a whole. In section 3 of the paper we examine the metropolitan area-wide results based on the sums and averages across all 100 metro areas, and compare these with the national totals and averages. In section 4 we present metropolitan area specific footprints and examine the considerable variation that is found to exist across individual metro areas. In doing so we pay particular attention to the effects that urban form might have on these differences. Finally, section 5 provides a summary of major findings, and a list of caveats that need to be borne in mind when using the results due to known limitations in the data sources used.

Evaluation study of building-resolved urban dispersion models  

SciTech Connect

For effective emergency response and recovery planning, it is critically important that building-resolved urban dispersion models be evaluated using field data. Several full-physics computational fluid dynamics (CFD) models and semi-empirical building-resolved (SEB) models are being advanced and applied to simulating flow and dispersion in urban areas. To obtain an estimate of the current state-of-readiness of these classes of models, the Department of Homeland Security (DHS) funded a study to compare five CFD models and one SEB model with tracer data from the extensive Midtown Manhattan field study (MID05) conducted during August 2005 as part of the DHS Urban Dispersion Program (UDP; Allwine and Flaherty 2007). Six days of tracer and meteorological experiments were conducted over an approximately 2-km-by-2-km area in Midtown Manhattan just south of Central Park in New York City. A subset of these data was used for model evaluations. The study was conducted such that an evaluation team, independent of the six modeling teams, provided all the input data (e.g., building data, meteorological data and tracer release rates) and run conditions for each of four experimental periods simulated. Tracer concentration data for two of the four experimental periods were provided to the modeling teams for their own evaluation of their respective models to ensure proper setup and operation. Tracer data were not provided for the second two experimental periods to provide for an independent evaluation of the models. The tracer concentrations resulting from the model simulations were provided to the evaluation team in a standard format for consistency in inter-comparing model results. An overview of the model evaluation approach will be given followed by a discussion on the qualitative comparison of the respective models with the field data. Future model developments efforts needed to address modeling gaps identified from this study will also be discussed.

An environmental pressure index proposal for urban development planning based on the analytic network process  

SciTech Connect

This paper introduces a new approach to prioritize urban planning projects according to their environmental pressure in an efficient and reliable way. It is based on the combination of three procedures: (i) the use of environmental pressure indicators, (ii) the aggregation of the indicators in an Environmental Pressure Index by means of the Analytic Network Process method (ANP) and (iii) the interpretation of the information obtained from the experts during the decision-making process. The method has been applied to a proposal for urban development of La Carlota airport in Caracas (Venezuela). There are three options which are currently under evaluation. They include a Health Club, a Residential Area and a Theme Park. After a selection process the experts chose the following environmental pressure indicators as ANP criteria for the project life cycle: used land area, population density, energy consumption, water consumption and waste generation. By using goal-oriented questionnaires designed by the authors, the experts determined the importance of the criteria, the relationships among criteria, and the relationships between the criteria and the urban development alternatives. The resulting data showed that water consumption is the most important environmental pressure factor, and the Theme Park project is by far the urban development alternative which exerts the least environmental pressure on the area. The participating experts coincided in appreciating the technique proposed in this paper is useful and, for ranking ordering these alternatives, an improvement from traditional techniques such as environmental impact studies, life-cycle analysis, etc.

Urban land use, air toxics and public health: Assessing hazardous exposures at the neighborhood scale  

Science Conference Proceedings (OSTI)

Land use data are increasingly understood as important indicators of potential environmental health risk in urban areas where micro-scale or neighborhood level hazard exposure data are not routinely collected. This paper aims to offer a method for estimating the distribution of air toxics in urban neighborhoods using land use information because actual air monitoring data rarely exist at this scale. Using Geographic Information System spatial modeling tools, we estimate air toxics concentrations across neighborhoods in New York City and statistically compare our model with the US Environmental Protection Agency's National Air Toxic Assessment and air monitoring data across three NYC neighborhoods. We conclude that land use data can act as a good proxy for estimating neighborhood scale air toxics, particularly in the absence of monitoring data. In addition, the paper suggests that land use data can expand the reach of environmental impact assessments that routinely exclude analyses of potential exposures to urban air toxics at the neighborhood scale.

Analysis of sheltering and evacuation strategies for an urban nuclear detonation scenario.  

SciTech Connect

Development of an effective strategy for shelter and evacuation is among the most important planning tasks in preparation for response to a low yield, nuclear detonation in an urban area. This study examines shelter-evacuate policies and effectiveness focusing on a 10 kt scenario in Los Angeles. The goal is to provide technical insights that can support development of urban response plans. Results indicate that extended shelter-in-place can offer the most robust protection when high quality shelter exists. Where less effective shelter is available and the fallout radiation intensity level is high, informed evacuation at the appropriate time can substantially reduce the overall dose to personnel. However, uncertainties in the characteristics of the fallout region and in the exit route can make evacuation a risky strategy. Analyses indicate that only a relatively small fraction of the total urban population may experience significant dose reduction benefits from even a well-informed evacuation plan.

Urban Integrated Industrial Cogeneration Systems Analysis. Phase II final report  

SciTech Connect

Through the Urban Integrated Industrial Cogeneration Systems Analysis (UIICSA), the City of Chicago embarked upon an ambitious effort to identify the measure the overall industrial cogeneration market in the city and to evaluate in detail the most promising market opportunities. This report discusses the background of the work completed during Phase II of the UIICSA and presents the results of economic feasibility studies conducted for three potential cogeneration sites in Chicago. Phase II focused on the feasibility of cogeneration at the three most promising sites: the Stockyards and Calumet industrial areas, and the Ford City commercial/industrial complex. Each feasibility case study considered the energy load requirements of the existing facilities at the site and the potential for attracting and serving new growth in the area. Alternative fuels and technologies, and ownership and financing options were also incorporated into the case studies. Finally, site specific considerations such as development incentives, zoning and building code restrictions and environmental requirements were investigated.

Modeling the Dynamics of Desakota Regions: Global - Local Nexus in the Taipei Metropolitan Area  

E-Print Network (OSTI)

Since the 1970s, Asia has experienced rapid urbanization processes, which are distinct from U.S. society, and the direction of Asian urbanization is more strongly affected by economic globalization. The desakota model, proposed by McGee and Ginsburg in 1991, focuses on how internal domestic and local forces drive the specific rural-urban transformation in Asia. However, the McGee-Ginsburg model does not emphasize the importance of globalization on Asian urbanization. To fill the gap, this study develops a GIS-based CA framework based on the desakota model to not only simulate the unique urbanization processes in Asia but also integrate the influence of globalization into Asian urban dynamics. Three approaches are developed in the CA simulation: 1) physical constraints and land-use classification from remotely sensed images in 1993, 2000, and 2008, are incorporated into micro-scale transformation; 2) population dynamics, shifts of economic activities, and foreign direct investment (FDIs), a representative of the impact of globalization, are applied for multi-scale interconnection; 3) the Monte Carlo mechanism is finally introduced to combine the above two approaches and implement the simulation process. The Taipei metropolitan area, a rapid urbanizing region that highly interacts with the global economy in Asia, is chosen to examine this model. The CA simulation model establishes a strong interaction between FDIs, an indicator representing impacts of globalization, and the dazzling Asian urban model. The combination of multi-scale economic factors and micro-scale land-use transformation also reveals how urban growth of the Taipei metropolis in recent years fits the characterization of the desakota model, and how desakota regions, the growth generators, interact with city cores. As a result, the research not only successfully links the influence of globalization with the desakota model and simulates urban dynamics of Asian cities but also provides scenarios of different FDI inputs for governments to better handle urban growth with global impacts under the deep economic recession since 2007.

Perception of principals in the southern, urban U.S. and eastern, urban China regarding the selection, preparation, and professional development of elementary principals  

E-Print Network (OSTI)

An effective principal is the catalyst for an effective school. For this reason, it is imperative that education stakeholders all over the world become responsible for addressing the selection, preparation and development of principals. The purpose of this study is to explore the similarities and differences in the selection process, preparation programs and the professional development practices as perceived by elementary school principals in urban public schools in the southern U.S and urban public schools in eastern China. The naturalistic paradigm of inquiry was used to frame the study and acquire and analyze data. The sample consisted of fourteen elementary school principals in a southern, urban area in the U.S. and an eastern, urban area in China selected via a purposive sample. The researcher visited their campuses between September, 2004 and January, 2005. Intensive interviews and observations were used to gather information from principals in American and Chinese urban elementary schools. Data from interviews were unitized into categories. Some of the conclusions included: ?? The American respondents indicated that current admission criteria for entrance into educational leadership programs were not sufficient for identifying a candidate??s aptitude for being a successful principal. ?? The Chinese principals believed that most selected Chinese principals are successful school leaders. ?? The American principals were satisfied with the effectiveness of the university preparation programs. ?? The Chinese principals were not satisfied with the effectiveness of classroom instruction of preparation programs. ?? The American principals felt that their professional development programs were helpful for improving their practice and their schools. ?? The Chinese principals were not satisfied with the effectiveness of the professional development programs. ?? Similarities and differences exist between the American and Chinese respondents?? perceptions of selection, preparation, and professional development.

Pathways for the Oxidation of Sarin in Urban Atmospheres  

Science Conference Proceedings (OSTI)

Terrorists have threatened and carried out chemicalhiological agent attacks on targets in major cities. The nerve agent sarin figured prominently in one well-publicized incident. Vapors disseminating from open containers in a Tokyo subway caused thousands of casualties. High-resolution tracer transport modeling of agent dispersion is at hand and will be enhanced by data on reactions with components of the urban atmosphere. As a sample of the level of complexity currently attainable, we elaborate the mechanisms by which sarin can decompose in polluted air. A release scenario is outlined involving the passage of a gas-phase agent through a city locale in the daytime. The atmospheric chemistry database on related organophosphorus pesticides is mined for rate and product information. The hydroxyl,radical and fine-mode particles are identified as major reactants. A review of urban air chernistry/rnicrophysics generates concentration tables for major oxidant and aerosol types in both clean and dirty environments. Organic structure-reactivity relationships yield an upper limit of 10-1' cm3 molecule-' S-* for hydrogen abstraction by hydroxyl. The associated midday loss time scale could be as little as one hour. Product distributions are difficult to define but may include nontoxic organic oxygenates, inorganic phosphorus acids, sarin-like aldehydes, and nitrates preserving cholinergic capabilities. Agent molecules will contact aerosol surfaces in on the order of minutes, with hydrolysis and side-chain oxidation as likely reaction channels.

An augmented reality system for military operations in urban terrain  

E-Print Network (OSTI)

Many future military operations are expected to occur in urban environments. These complex, 3D battlefields introduce many challenges to the dismounted warfighter. Better situational awareness is required for effective operation in urban environments. However, delivering this information to the dismounted warfighter is extremely difficult. For example, maps draw a user's attention away from the environment and cannot directly represent the three-dimensional nature of the terrain. To overcome these difficulties, we are developing the Battlefield Augmented Reality System (BARS). The system consists of a wearable computer, a wireless network system, and a tracked see-through head-mounted display (HMD). The computer generates graphics that, from the user's perspective, appear to be aligned with the actual environment. For example, a building could be augmented to show its name, a plan of its interior, icons to represent reported sniper locations, and the names of adjacent streets. This paper surveys the current state of development of BARS and describes ongoing research efforts. We describe four major research areas. The first is the development of an effective, efficient user interface for displaying data and processing user inputs. The second is the capability for collaboration between multiple BARS users and other systems. Third, we describe the current hardware for both a mobile and indoor prototype system. Finally, we

Lifecycle Assessment of Beijing-Area Building Energy Use and Emissions: Summary Findings and Policy Applications  

SciTech Connect

Buildings are at the locus of three trends driving China's increased energy use and emissions: urbanization, growing personal consumption, and surging heavy industrial production. Migration to cities and urban growth create demand for new building construction. Higher levels of per-capita income and consumption drive building operational energy use with demand for higher intensity lighting, thermal comfort, and plug-load power. Demand for new buildings, infrastructure, and electricity requires heavy industrial production. In order to quantify the implications of China's ongoing urbanization, rising personal consumption, and booming heavy industrial sector, this study presents a lifecycle assessment (LCA) of the energy use and carbon emissions related to residential and commercial buildings. The purpose of the LCA model is to quantify the impact of a given building and identify policy linkages to mitigate energy demand and emissions growth related to China's new building construction. As efficiency has become a higher priority with growing energy demand, policy and academic attention to buildings has focused primarily on operational energy use. Existing studies estimate that building operational energy consumption accounts for approximately 25% of total primary energy use in China. However, buildings also require energy for mining, extracting, processing, manufacturing, and transporting materials, as well as energy for construction, maintenance, and decommissioning. Building and supporting infrastructure construction is a major driver of industry consumption--in 2008 industry accounted for 72% of total Chinese energy use. The magnitude of new building construction is large in China--in 2007, for example, total built floor area reached 58 billion square meters. During the construction boom in 2007 and 2008, more than two billion m{sup 2} of building space were added annually; China's recent construction is estimated to account for half of global construction. Lawrence Berkeley National Laboratory (LBNL) developed an integrated LCA model to capture the energy and emissions implications of all aspects of new buildings from material mining through construction, operations, and decommissioning. Over the following four sections, this report describes related existing research, the LBNL building LCA model structure and results, policy linkages of this lifecycle assessment, and conclusions and recommendations for follow-on work. The LBNL model is a first-order approach to gathering local data and applying lifecycle assessment to buildings in the Beijing area--it represents one effort among a range of established, predominantly American and European, LCA models. This report identifies the benefits, limitations, and policy applications of lifecycle assessment modeling for quantifying the energy and emissions impacts of specific residential and commercial buildings.

Inhalation of primary motor vehicle emissions: Effects of urbanpopulation and land area  

SciTech Connect

Urban population density can influence transportation demand, as expressed through average daily vehicle-kilometers traveled per capita (VKT). In turn, changes in transportation demand influence total passenger vehicle emissions. Population density can also influence the fraction of total emissions that are inhaled by the exposed urban population. Equations are presented that describe these relationships for an idealized representation of an urban area. Using analytic solutions to these equations, we investigate the effect of three changes in urban population and urban land area (infill, sprawl, and constant-density growth) on per capita inhalation intake of primary pollutants from passenger vehicles. The magnitude of these effects depends on density-emissions elasticity ({var_epsilon}{sub e}), a normalized derivative relating change in population density to change in vehicle emissions. For example, if urban population increases, per capita intake is less with infill development than with constant-density growth if {var_epsilon}{sub e} is less than -0.5, while for {var_epsilon}{sub e} greater than -0.5 the reverse is true.

Towards sustainable settlement growth: A new multi-criteria assessment for implementing environmental targets into strategic urban planning  

Science Conference Proceedings (OSTI)

For nearly one decade, the German political and research-agenda has been to a large extent determined by the ongoing question of how to limit the expansion of settlement areas around cities in order to preserve natural resources, make settlement growth more sustainable and to strengthen the re-use of existing inner-urban areas (see a.o. Koetter et al. 2009a, 2010; Schetke et al. 2009, 2010b). What is already under discussion within the international literature are the recommendations of the German Council for Sustainability to quantitatively reduce the daily greenfield consumption from the current rate of over 100 ha per day to a rate of 30 ha per day in 2020 and to bring urban infill development up to a ratio of 3:1 with greenfield development (German Council for Sustainability, 2004).). This paper addresses the added value beyond those abstract political targets and presents an innovative, multi-criteria assessment (MCA) of greenfield and infill sites to evaluate their sustainability and resource efficiency. MCA development and its incorporation into a Decision Support System (DSS) were accomplished by utilising a stakeholder-driven approach. The resulting tool can be applied in preparing and revising land-use plans. The paper presents the concept and the development process of the MCA-DSS. Test runs with planners prove that the evaluation of potential housing sites using individually weighted environmental indicators helps to identify those strategies of housing development that accord most closely with sustainability goals. The tests further show that the development of greenfield sites generally exhibits less sustainability than that of infill sites. - Highlights: Black-Right-Pointing-Pointer This paper presents an innovative, multi-criteria assessment (MCA) of greenfield and infill sites.

Geothermal resource area 11, Clark County area development plan  

DOE Green Energy (OSTI)

Geothermal Resource Area 11 includes all of the land in Clark County, Nevada. Within this area are nine geothermal anomalies: Moapa Area, Las Vegas Valley, Black Canyon, Virgin River Narrows, Roger's Springs, Indian Springs, White Rock Springs, Brown's Spring, and Ash Creek Spring. All of the geothermal resources in Clark County have relatively low temperatures. The highest recorded temperature is 145{sup 0}F at Black Canyon. The temperatures of the other resources range from 70 to 90{sup 0}F. Because of the low temperature of the resources and, for the most part, the distance of the resources from any population base, the potential for the development of the resources are considered to be somewhat limited.

The Impact of Urban Form and Housing Characteristics on Residential Energy Use  

E-Print Network (OSTI)

Cities and their characteristics of energy use play an important role in climate change. While there is abundant research about the impact of energy use on transportation the impact of urban form and housing characteristics on residential energy use has not been considered widely. There is certainly a need to take a closer look about the residential energy use and housing relationships to identify planning implications. This study examines the relationship between various urban form, housing characteristics and the energy use that result from residential electricity and fuel use. Ordinary least squares regression methods are used to measure the correlations between energy consumption and variables describing housing and urban form characteristics in the metropolitan statistical areas in the United States. After controlling for differences in energy price and income, a positive relationship between residential energy consumption and a history of greater rates of land conversion was found. This study also finds significantly higher energy use associated with a greater incidence of detached single-family housing when compared against high-rise buildings. A correlation between increased rate of row housing and lower energy use was found as well. This study can contribute to a literature that can help planners to create more environmentally- friendly cities by contributing to the understanding of the impacts that certain energy- related housing characteristics have on the sustainability of a city. The literature regarding smart growth and new urbanism should explore potential impacts on household energy consumption in its discussion of urban planning along with considering impacts on transportation related energy use.

Effectiveness And Welfare Impacts Of Alternative Policies To Address Atmospheric Pollution In URBAN ROAD TRANSPORT  

E-Print Network (OSTI)

In this paper we compare the effectiveness and welfare effects of alternative fuel efficiency, environmental and transport policies for a given urban area. The urban transport activities are represented as a set of interrelated markets, one for each mode of transport and type of vehicle. For each market, four different marginal external costs are computed in the present equilibrium: air pollution, accidents, noise and congestion. The gap between marginal social costs and prices shows that congestion and unpaid parking are the dominant sources of inefficiencies. Air pollution costs are significant as well. The effects of a typical air quality policy (regulation of car emission technology) and two typical fuel based policies (minimum fuel efficiency policy and fuel taxes) are compared with the effects of three alternative transport policies (full external cost pricing, cordon pricing, parking charges). Regulation of emission technology and of fuel efficiency do not necessarily lead to welfare gains, whereas transport pricing policies yield substantial gains for the urban area under study.

Urban modeling based on segmentation and regularization of airborne lidar point clouds  

E-Print Network (OSTI)

This paper presents an approach to process raw lidar 3-D point clouds over urban area and extract terrain, buildings and other urban features. In the initial step, “non-ground points ” are separated from ground points using a one dimensional filtering process based on the slope between two consecutive points in the point cloud and the terrain elevation in the vicinity of the points. In the next step, the non-ground point dataset is processed to segment individual buildings. This is accomplished by using a 3-D regional growing approach. At the end of this step, each lidar point is attributed to a building. The first step towards building reconstruction is to obtain an approximate footprint of the building, which is accomplished by extracting the points on the building boundary by a modified convex hull algorithm. Once the footprint boundary points are found, their edges are regularized by using a least squares model to form the final building shape. Mathematic formulation of 3D region growing and boundary regularization is presented. Tests results of reconstructed buildings over complex urban areas are reported. 1.

Abundance and Distribution of Africanized Honey Bees in an Urban Environments  

E-Print Network (OSTI)

Africanized honey bees (AHB) are a hybrid between African and European honey bees (EHB). Compared to the EHB, AHB exhibit more intense, defensive behaviors but nevertheless provide the same important ecosystem service--pollination. AHB have been found in Tucson, AZ. since 1993. It is important to understand the population ecology of AHB for several reasons. Most directly, the behavioral traits retained from African bees present public safety and health risk. AHB are easily agitated; even slight disturbances (e.g., human movements) can provoke attacks. Several hybridized bee traits (e.g., higher colony growth rates, reproduction at a smaller colony size, nesting in a wider range of cavity materials, etc.) also make them more adapted to urban landscapes. The overlap of habitats and resource-using of AHB with human significantly raise the risk of stinging incidents, especially in the areas of bee aggregation. Although the presence of AHB in urban environments may present a public safety and health risk, they do contribute to urban ecosystems substantially through pollination. The fact that AHB is a part of the urban ecosystem suggests a need for a better understanding of the relationship among climate factors, urban landscape characteristics, and AHB population dynamics. The goal of my dissertation was to understand population dynamics of AHB in urban environments using removal records of AHB colonies in water meter boxes. I have demonstrated useful methods and repeatable procedures to process, extract, and synthesize water meter box data which were not collected or sampled specifically for any ecological research. I also examined the spatio-temporal distributions of AHB colony removals in water meter boxes, and evaluated the effects of variations of temperature and precipitation on observed patterns. Then, I investigated the linkage between spatial patterns of AHB colonies and urban landscape characteristics by evaluating densities of water meter boxes, AHB colony abundance, and colony occupancy among different land cover/land use types. Lastly, a conceptual model and quantitative models were developed to illustrate AHB population dynamics, particularly and the interactions among water meter boxes, alternative cavities, and honey bee colonies. Overall, the probabilities of AHB colonies selecting nesting sites can be influenced by: (1) the ratio of water meter boxes and alternative cavities; (2) the difference of vegetative attributes among locations associated with the preference of AHB in selecting new nesting sites.

Limit Cycle and Conserved Dynamics  

E-Print Network (OSTI)

We demonstrate that a potential coexists with limit cycle. Here the potential determines the final distribution of population. Our demonstration consists of three steps: We first show the existence of limit from a typical physical sciences setting: the potential is a type of Mexican hat type, with the strength of a magnetic field scale with the strength the potential gradient near the limit cycle, and the friction goes to zero faster than the potential near the limit cycle. Hence the dynamics at the limit cycle is conserved. The diffusion matrix is nevertheless finite at the limit cycle. Secondly, we construct the potential in the dynamics with limit cycle in a typical dynamical systems setting. Thirdly, we argue that such a construction can be carried out in a more general situation based on a method discovered by one of us. This method of dealing with stochastic differential equation is in general different from both Ito and Stratonovich calculus. Our result may be useful in many related applications, such as in the discussion of metastability of limit cycle and in the construction of Hopfield potential in the neural network computation.

FUEL CASK IMPACT LIMITER VULNERABILITIES  

Science Conference Proceedings (OSTI)

Cylindrical fuel casks often have impact limiters surrounding just the ends of the cask shaft in a typical 'dumbbell' arrangement. The primary purpose of these impact limiters is to absorb energy to reduce loads on the cask structure during impacts associated with a severe accident. Impact limiters are also credited in many packages with protecting closure seals and maintaining lower peak temperatures during fire events. For this credit to be taken in safety analyses, the impact limiter attachment system must be shown to retain the impact limiter following Normal Conditions of Transport (NCT) and Hypothetical Accident Conditions (HAC) impacts. Large casks are often certified by analysis only because of the costs associated with testing. Therefore, some cask impact limiter attachment systems have not been tested in real impacts. A recent structural analysis of the T-3 Spent Fuel Containment Cask found problems with the design of the impact limiter attachment system. Assumptions in the original Safety Analysis for Packaging (SARP) concerning the loading in the attachment bolts were found to be inaccurate in certain drop orientations. This paper documents the lessons learned and their applicability to impact limiter attachment system designs.

Retrofit Legislation at the Urban Level  

NLE Websites -- All DOE Office Websites (Extended Search)

Retrofit Legislation at the Urban Level Retrofit Legislation at the Urban Level In March, the city of Berkeley, California, passed new legislation that should serve as a model for local policies intended to keep energy dollars within the community while protecting the environment. The Commercial Energy Conservation Ordinance (CECO) is based on a similar ordinance that has been law since 1989 in San Francisco, Berkeley's neighbor across the Bay. San Francisco is currently the only other city in the world to have this type of legislation. As part of the Berkeley Municipal Code, CECO requires commercial buildings to undergo energy conservation retrofits when they are sold or substantially renovated. CECO was designed with the participation of LBL's Kristin Heinemeier, who also works with the Berkeley

NICKEL SPECIATION OF URBAN PARTICULATE MATTER  

SciTech Connect

A four-step sequential Ni extraction method, summarized in Table AB-1, was evaluated for identifying and quantifying the Ni species occurring in urban total suspended particulate (TSP) matter and fine particulate matter (<10 {micro}m [PM{sub 10}] and <2.5 {micro}m [PM{sub 2.5}] in aerodynamic diameter). The extraction method was originally developed for quantifying soluble, sulfidic, elemental, and oxidic forms of Ni that may occur in industrial atmospheres. X-ray diffraction (XRD) and x-ray absorption fine structure (XAFS) spectroscopy were used to evaluate the Ni species selectivity of the extraction method. Uncertainties in the chemical speciation of Ni in urban PM{sub 10} and PM{sub 2.5} greatly affect inhalation health risk estimates, primarily because of the large variability in acute, chronic, and cancer-causing effects for different Ni compounds.

Energy Saving Potentials and Air Quality Benefits of Urban HeatIslandMitigation  

SciTech Connect

Urban areas tend to have higher air temperatures than their rural surroundings as a result of gradual surface modifications that include replacing the natural vegetation with buildings and roads. The term ''Urban Heat Island'' describes this phenomenon. The surfaces of buildings and pavements absorb solar radiation and become extremely hot, which in turn warm the surrounding air. Cities that have been ''paved over'' do not receive the benefit of the natural cooling effect of vegetation. As the air temperature rises, so does the demand for air-conditioning (a/c). This leads to higher emissions from power plants, as well as increased smog formation as a result of warmer temperatures. In the United States, we have found that this increase in air temperature is responsible for 5-10% of urban peak electric demand for a/c use, and as much as 20% of population-weighted smog concentrations in urban areas. Simple ways to cool the cities are the use of reflective surfaces (rooftops and pavements) and planting of urban vegetation. On a large scale, the evapotranspiration from vegetation and increased reflection of incoming solar radiation by reflective surfaces will cool a community a few degrees in the summer. As an example, computer simulations for Los Angeles, CA show that resurfacing about two-third of the pavements and rooftops with reflective surfaces and planting three trees per house can cool down LA by an average of 2-3K. This reduction in air temperature will reduce urban smog exposure in the LA basin by roughly the same amount as removing the basin entire onroad vehicle exhaust. Heat island mitigation is an effective air pollution control strategy, more than paying for itself in cooling energy cost savings. We estimate that the cooling energy savings in U.S. from cool surfaces and shade trees, when fully implemented, is about $5 billion per year (about $100 per air-conditioned house).

Conversion of agricultural land to urban use  

SciTech Connect

The large amount of land lost each year to urbanization has led nearly all states to adopt legislation that grants tax preferences to agricultural land use. Several studies have analyzed the effects of such policies on the rate of land development and on the total amount of land eventually developed. However, these studies have only analyzed permanent tax-rate changes despite the fact that most such changes are temporary. A distinction is made in this study between temporary, permanent, anticipated, and unanticipated tax-rate increases. Using a hedonic approach, the elasticity of supply of urban fringe land in McHenry County, Illinois is estimated to be approximately 0.30, which indicates that the amount of land converted to urban use is unlikely to be affected much by these polices. The hedonic approach as usually implemented is shown to lead to inconsistent parameter estimates. A consistent estimation procedure is proposed that produces testable cross-equation restrictions. A restriction is implied in the empirical section of this study by the use of the Box-Cox transformation to generalize functional form; it is tested and is not rejected. However, little is known about the small-sample properties of this transformation. To rectify this, a Monte Carlo study is conducted of the performance of Lagrange Multiplier tests for incorrect functional form and heteroskedasticity in a model that uses this transformation.

A comparative study of O{sub 3} formation in the Houston urban and industrial plumes during the TEXAQS 2000 Study.  

SciTech Connect

Ozone formation in the Houston area during a period of high ozone concentrations that occurred on 29 August 2000 during the TexAQS 2000 study is examined to understand differences in the sources of O{sub 3} precursors and the rate and efficiency of ozone formation over the city of Houston and the industrialized Ship Channel region to the east of Houston. From late morning through late afternoon on 29 August, a period of stagnation occurred, allowing accumulation of O{sub 3} and product species separately over downtown Houston and the Houston Ship Channel. Three aircraft flights were made in the region, starting from about 0900 CST and extending to about 1700 CST. A localized plume of high O{sub 3} ranging between 120 and 200 ppb was observed over the Ship Channel on all of these aircraft flights. Over the same time period, O{sub 3} concentrations over the city were much lower ranging between 40 and 90 ppb. NO{sub x} concentrations measured in the two regions in the late morning were roughly the same, but hydrocarbon reactivities over the industrial area were much higher, by as much as a factor of 10. Photochemical box model calculations constrained by observations of NO{sub x}, hydrocarbons, O{sub 3}, and other stable species indicated that the instantaneous ozone formation rate was much lower (3-18 ppb/h) over downtown Houston than it was over the Ship Channel (3-80 ppb/h). The much faster O{sub 3} formation rates and higher concentrations observed over the Ship Channel are attributed to the much higher hydrocarbon reactivity, the majority of which was contributed by low molecular weight alkenes. These high hydrocarbon reactivities also caused O{sub 3} over the Ship Channel to be produced with much higher efficiency than over urban Houston. Comparison of photochemical product distributions suggests that O{sub 3} formation in the urban area is much more hydrocarbon limited than in the Ship Channel, consistent with the geographic distribution of major hydrocarbon sources in the area.

URBAN ATMOSPHERIC OBSERVATORY (UAO) FIRST PLANNING WORKSHOP, JANUARY 27-28-2003. WORKSHOP SUMMARY.  

SciTech Connect

The Urban Atmospheric Observatory (UAO) First Planning Workshop was held on 27-28 January 2003 at the Environmental Measurements Laboratory (EML) in downtown Manhattan, New York City. The meeting was well attended by local, state, and national administrators, as well as scientists and engineers from the national laboratories and academia. The real-time intensive UAO is a necessary step toward the development and validation of new technologies in support of the New York City emergency management and anti-terrorism effort. The real-time intensive UAO will be a dense array of meteorological instrumentation, remote sensing and satellite products and model output, as well as radiation detection, gamma spectrometer and aerosol measurements focused onto a small area in the heart of Manhattan. Such a test-bed, developed in a somewhat homogeneous urban area, and with a well-developed communication and data collection backbone, will be of immense utility for understanding how models of all scales can be improved and how they can best be integrated into the city's emergency program. The goal of the First Planning Workshop was to bring together a small group of experts in the fields of urban meteorology, modeling from mesoscale to fine-mesh computational fluid dynamics, instrumentation, communications and visualization, in order to (1) establish the importance of the observational program, (2) define the most efficient and cost-effective design for the program, (3) define needed intensive observational efforts and establish a schedule, and (4) define the importance of the UAO in emergency operations. The workshop achieved its goals with the enthusiastic participation of over forty persons. There was a synthesis of ideas towards a world-class facility that would benefit both immediate emergency management activities and, over an extended time, the entire field of urban meteorology and contaminant dispersion modeling.

Passive fault current limiting device  

DOE Patents (OSTI)

A passive current limiting device and isolator is particularly adapted for use at high power levels for limiting excessive currents in a circuit in a fault condition such as an electrical short. The current limiting device comprises a magnetic core wound with two magnetically opposed, parallel connected coils of copper, a high temperature superconductor or other electrically conducting material, and a fault element connected in series with one of the coils. Under normal operating conditions, the magnetic flux density produced by the two coils cancel each other. Under a fault condition, the fault element is triggered to cause an imbalance in the magnetic flux density between the two coils which results in an increase in the impedance in the coils. While the fault element may be a separate current limiter, switch, fuse, bimetal strip or the like, it preferably is a superconductor current limiter conducting one-half of the current load compared to the same limiter wired to carry the total current of the circuit. The major voltage during a fault condition is in the coils wound on the common core in a preferred embodiment. 6 figs.

Infrastructure Ecology for Sustainable and Resilient Urban Infrastructure Design  

DOE Green Energy (OSTI)

The population growth coupled with increasing urbanization is predicted to exert a huge demand on the growth and retrofit of urban infrastructure, particularly in water and energy systems. The U.S. population is estimated to grow by 23% (UN, 2009) between 2005 and 2030. The corresponding increases in energy and water demand were predicted as 14% (EIA, 2009) and 20% (Elcock, 2008), respectively. The water-energy nexus needs to be better understood to satisfy the increased demand in a sustainable manner without conflicting with environmental and economic constraints. Overall, 4% of U.S. power generation is used for water distribution (80%) and treatment (20%). 3% of U.S. water consumption (100 billion gallons per day, or 100 BGD) and 40% of U.S. water withdrawal (340 BGD) are for thermoelectric power generation (Goldstein and Smith, 2002). The water demand for energy production is predicted to increase most significantly among the water consumption sectors by 2030. On the other hand, due to the dearth of conventional water sources, energy intensive technologies are increasingly in use to treat seawater and brackish groundwater for water supply. Thus comprehending the interrelation and interdependency between water and energy system is imperative to evaluate sustainable water and energy supply alternatives for cities. In addition to the water-energy nexus, decentralized or distributed concept is also beneficial for designing sustainable water and energy infrastructure as these alternatives require lesser distribution lines and space in a compact urban area. Especially, the distributed energy infrastructure is more suited to interconnect various large and small scale renewable energy producers which can be expected to mitigate greenhouse gas (GHG) emissions. In the case of decentralized water infrastructure, on-site wastewater treatment facility can provide multiple benefits. Firstly, it reduces the potable water demand by reusing the treated water for non-potable uses and secondly, it also reduces the wastewater load to central facility. In addition, lesser dependency on the distribution network contributes to increased reliability and resiliency of the infrastructure. The goal of this research is to develop a framework which seeks an optimal combination of decentralized water and energy alternatives and centralized infrastructures based on physical and socio-economic environments of a region. Centralized and decentralized options related to water, wastewater and stormwater and distributed energy alternatives including photovoltaic (PV) generators, fuel cells and microturbines are investigated. In the context of the water-energy nexus, water recovery from energy alternatives and energy recovery from water alternatives are reflected. Alternatives recapturing nutrients from wastewater are also considered to conserve depleting resources. The alternatives are evaluated in terms of their life-cycle environmental impact and economic performance using a hybrid life cycle assessment (LCA) tool and cost benefit analysis, respectively. Meeting the increasing demand of a test bed, an optimal combination of the alternatives is designed to minimize environmental and economic impacts including CO2 emissions, human health risk, natural resource use, and construction and operation cost. The framework determines the optimal combination depending on urban density, transmission or conveyance distance or network, geology, climate, etc. Therefore, it will be also able to evaluate infrastructure resiliency against physical and socio-economic challenges such as population growth, severe weather, energy and water shortage, economic crisis, and so on.

Southern Nevada residents` views about the Yucca Mountain high-level nuclear waste repository and related issues: A comparative analysis of urban and rural survey data  

SciTech Connect

two separate surveys were undertaken in 1988 to ascertain southern Nevadans` views about the Yucca Mountain repository and related issues. The first of these studies focused on the attitudes and perceptions of residents in the Las Vegas metropolitan area. The second study addressed similar issues, but focused on the views of residents in six rural communities in three counties adjacent to the Yucca Mountain site. However, parallel findings from the two data sets have not been jointly analyzed in order to identify ways in which the views and orientations of residents in the rural and urban study areas may be similar or different. The purpose of this report is to develop and present a comparative assessment of selected issues addressed in the rural and urban surveys. Because both urban and rural populations would potentially be impacted by the Yucca Mountain repository, such an analysis will provide important insights into possible repository impacts on the well-being of residents throughout southern Nevada.

Urban Water Conservation along the Rio Grande  

E-Print Network (OSTI)

Not long ago, conversations on urban water demand were not only rare but dull. Today, especially in the West and Southwest, these conversations can turn into heated debates. The question of who has enough water for the future has pitted urban interests against agriculture and financial resources against cultural values. Water supply is finite, even if it is part of a cycle. Water may be plentiful in some places and scarce in others. Until we are ready to make water conservation a pattern of behavior to use less water, our demand will continue to grow as our population grows. Although water conservation is not an answer to all growth, it does offer an alternative to acquiring some new water supplies. Water conservation is almost always the least expensive water supply alternative. Water conservation can have two definitions. First and most often, conservation is considered a reduction in the amount of water used. Each person uses less. An alternative definition implies more efficient use of water. We waste less. Less waste can be attributed to best management practices, more efficient hardware or literally less water running into the streets from irrigation systems. Urban water conservation incorporates watersaving measures and incentives for the home, on the landscape and throughout the city water distribution system. It is easy to differentiate between water-saving measures and incentives. A water-saving measure such as a water-efficient toilet reduces the amount used each and every time it is flushed. Or, a rain sensor turns off a sprinkler system during rain showers. In contrast, incentives encourage the wise use of water through education, ordinances or scheduling. Educational programs suggest water reductions in the landscape, ordinances mandate how much turf is planted, and schedules tell homeowners when to irrigate. Combined, measures and incentives provide a water conservation program.

Urban Policies and Earthquake Risk Mitigation  

SciTech Connect

The paper aims at proposing some considerations about some recent experiences of research carried out on the theme of earthquake risk mitigation and combining policies and actions of mitigation with urban development strategies. The objective was to go beyond the classical methodological approach aiming at defining a 'technical' evaluation of the earthquake risk through a procedure which can correlate the three 'components' of danger, exposure and vulnerability. These researches experiment, in terms of methodology and application, with a new category of interpretation and strategy: the so-called Struttura Urbana Minima (Minimum urban structure).Actually, the introduction of the Struttura Urbana Minima establishes a different approach towards the theme of safety in the field of earthquake risk, since it leads to a wider viewpoint, combining the building aspect of the issue with the purely urban one, involving not only town planning, but also social and managerial implications.In this sense the constituent logic of these researches is strengthened by two fundamental issues:- The social awareness of earthquake;- The inclusion of mitigation policies in the ordinary strategies for town and territory management. Three main aspects of the first point, that is of the 'social awareness of earthquake', characterize this issue and demand to be considered within a prevention policy:- The central role of the risk as a social production,- The central role of the local community consent,- The central role of the local community capability to planTherefore, consent, considered not only as acceptance, but above all as participation in the elaboration and implementation of choices, plays a crucial role in the wider issue of prevention policies.As far as the second point is concerned, the inclusion of preventive mitigation policies in ordinary strategies for the town and territory management demands the identification of criteria of choice and priorities of intervention and, as a consequence, the opportunity to promote an approach to the theme of mitigation policies realized through strategic principles and systemic logics able to shift the problem from the building to the town. The critical aspects of this theme are tied to three main issues:- The sharing of the way of interpreting town planning,- The integration of multiple objectives in one intervention tool,- The measures which can be adopted for an effective prevention policy.The above-mentioned elements have inspired these researches experimented on Calabrian towns.In particular, in this paper the experience carried out on Reggio Calabria is proposed. Its cultural roots derive from the principles and criteria experimented in small Calabrian towns, but it modifies them according to the complexity of the urban settlement, introducing also some experimental concepts and methodological approaches.

Impacts of urban transportation mode split on CO{sub 2} emissions in Jinan, China.  

Science Conference Proceedings (OSTI)

As the world's largest developing country, China currently is undergoing rapid urbanization and motorization, which will result in far-reaching impacts on energy and the environment. According to estimates, energy use and carbon emissions in the transportation sector will comprise roughly 30% of total emissions by 2030. Since the late 1990s, transportation-related issues such as energy, consumption, and carbon emissions have become a policy focus in China. To date, most research and policies have centered on vehicle technologies that promote vehicle efficiency and reduced emissions. Limited research exists on the control of greenhouse gases through mode shifts in urban transportation - in particular, through the promotion of public transit. The purpose of this study is to establish a methodology to analyze carbon emissions from the urban transportation sector at the Chinese city level. By using Jinan, the capital of China's Shandong Province, as an example, we have developed an analytical model to simulate energy consumption and carbon emissions based on the number of trips, the transportation mode split, and the trip distance. This model has enabled us to assess the impacts of the transportation mode split on energy consumption and carbon emissions. Furthermore, this paper reviews a set of methods for data collection, estimation, and processing for situations where statistical data are scarce in China. This paper also describes the simulation of three transportation system development scenarios. The results of this study illustrate that if no policy intervention is implemented for the transportation mode split (the business-as-usual (BAU) case), then emissions from Chinese urban transportation systems will quadruple by 2030. However, a dense, mixed land-use pattern, as well as transportation policies that encourage public transportation, would result in the elimination of 1.93 million tons of carbon emissions - approximately 50% of the BAU scenario emissions.

Application of a Sequential Reaction Model to PANS and Aldehyde Measurements in Two Urban Areas  

SciTech Connect

Measurements of peroxycarboxylic nitric anhydrides (= PAN, PPN, MPAN) and aldehydes (acetaldehyde, propanal, and methacrolein) were made at Nashville, Tennessee, in 1999 and Houston, Texas, in 2000. The data were interpreted with a sequential reaction model that included reaction of aldehydes with hydroxl radical and formation or loss of PANs mediated by peroxyacyl radicals. The comparison of the measured ratios with those predicted by the model showed disagreement for PAN/acetaldehyde and PPN/propanal in Nashville but agreement in Houston. These features are consistent with the relative importance of isoprene to PAN formation at each site.

Integration of supply and demand for water in central Illinois urban areas. Research report  

Science Conference Proceedings (OSTI)

Water demand functions were estimated using two sets of data for Central Illinois -- community-wide data and household data. The community-wide data consist of total residential consumption for each of four pre-selected medium-sized cities in Central Illinois. The household data consist of residents from five cities who responded to a mail survey. The study investigates comparability of parameter estimates from the two approaches. If the parameter estimates are comparable, it would suggest water demand estimates need not require costly and time-consuming household surveys. Estimates of price elasticity are negative and less than unitary based on the two data sets used. The estimated price elasticity based on community-wide data is -.037, while using household data estimated price elasticities are in the range from -.14 to -.16. The reasons for these differences are not immediately apparent and warrant further investigation.

Earthquake Risk Management of Underground Lifelines in the Urban Area of Catania  

SciTech Connect

Lifelines typically include the following five utility networks: potable water, sewage natural gas, electric power, telecommunication and transportation system. The response of lifeline systems, like gas and water networks, during a strong earthquake, can be conveniently evaluated with the estimated average number of ruptures per km of pipe. These ruptures may be caused either by fault ruptures crossing, or by permanent deformations of the soil mass (landslides, liquefaction), or by transient soil deformations caused by seismic wave propagation. The possible consequences of damaging earthquakes on transportation systems may be the reduction or the interruption of traffic flow, as well as the impact on the emergency response and on the recovery assistance. A critical element in the emergency management is the closure of roads due to fallen obstacles and debris of collapsed buildings.The earthquake-induced damage to buried pipes is expressed in terms of repair rate (RR), defined as the number of repairs divided by the pipe length (km) exposed to a particular level of seismic demand; this number is a function of the pipe material (and joint type), of the pipe diameter and of the ground shaking level, measured in terms of peak horizontal ground velocity (PGV) or permanent ground displacement (PGD). The development of damage algorithms for buried pipelines is primarily based on empirical evidence, tempered with engineering judgment and sometimes by analytical formulations.For the city of Catania, in the present work use has been made of the correlation between RR and peak horizontal ground velocity by American Lifelines Alliance (ALA, 2001), for the verifications of main buried pipelines. The performance of the main buried distribution networks has been evaluated for the Level I earthquake scenario (January 11, 1693 event I = XI, M 7.3) and for the Level II earthquake scenario (February 20, 1818 event I = IX, M 6.2).Seismic damage scenario of main gas pipelines and water has been obtained, with PGV values calculated for level I and level II earthquake scenarios.

I radiocollared 99 skunks from the Houston, Texas metropolitan area and monitored skunk movements from March 2004–June 2006. To accelerate progress of this study, I captured 93 of 99 skunks using a dip net. Dip netting allowed for an effective collection alternative to cage trapping. Movement data indicated a strong preference for short grass areas (82%), however, habitat use changed to remote, brushy areas when temperatures were ?7C. Habitat use during the year was different (P = 0.001), with December 2004, January 2005, and February 2005 significantly (P = 0.001) different from one another. Additionally, habitat use during December 2005, February 2006, and March 2006 were significantly different (P = 0.045, P =0.098, and P =0.003, respectively). Data from 20 skunks, covering multiple seasons, were analyzed for home range use. I found male home range use averaged 255 ha (217–345), while females averaged 126 ha (60–218). Male range use was significantly larger than females (P = 0.005). No significant seasonal movements were observed. Lastly, I conducted a survey of 297 Texas primary care medical providers to assess their knowledge of rabies vaccine procedures and their experience with rabies vaccines. Small town providers within the oral rabies vaccination baiting zone were more aware of rabies prophylaxis (P 95% of 297) rarely saw patients for rabies prophylaxis. Survey data indicated providers have minimal, if any, experience with acquiring and administering rabies prophylaxis. My data suggests that an effective oral rabies vaccination program could be established within urban areas by using short grass area baiting strategies during the fall season, using dip net capturing for faster surveillance collection, and by initiating a rabies education program targeted at Texas’ primary care physicians and their staff.

Effectiveness of Urban Shelter-in-Place. III: Commercial Districts  

SciTech Connect

In the event of a toxic chemical release to the atmosphere, shelter-in-place (SIP) is an emergency response option available to protect public health. This paper is the last in a three-part series that examines the effectiveness of SIP at reducing adverse health effects in communities. We model a hypothetical chemical release in an urban area, and consider SIP effectiveness in protecting occupants of commercial buildings. Building air infiltration rates are predicted from empirical data using an existing model. We consider the distribution of building air infiltration rates both with mechanical ventilation systems turned off and with the systems operating. We also consider the effects of chemical sorption to indoor surfaces and nonlinear chemical dose-response relationships. We find that commercial buildings provide effective shelter when ventilation systems are off, but that any delay in turning off ventilation systems can greatly reduce SIP effectiveness. Using a two-zone model, we find that there can be substantial benefit by taking shelter in the inner parts of a building that do not experience direct air exchange with the outdoors. Air infiltration rates vary substantially among buildings and this variation is important in quantifying effectiveness for emergency response. Community-wide health metrics, introduced in the previous papers in this series, can be applied in pre-event planning and to guide real-time emergency response.

Life in the Fast Lane: Road Crossing Behavior of Mule Deer in a Wildland-Urban Interface  

Science Conference Proceedings (OSTI)

In 2009, approximately 260,000 animal-vehicle collisions were reported in the United States, resulting in 12,000 human injuries and 173 human fatalities. Research has focused on identifying factors associated with high densities of animal-vehicle collisions, including variables such as traffic speed and volume, road design, topographic features, vegetative cover, and local deer or elk (Cervus elaphus) abundance. The purposes of this study were to document how often and where mule deer (Odocoileus hemionus) crossed roads in a western United States wildland-urban interface area, and to relate deer road-crossing behavior to deer-vehicle collision locations. Seven adult mule deer (four males [M] and three females [F]) were captured and collared with GPS-enabled collars during December 2001 and January 2002. Five of the seven deployed collars were recovered. None of the roads in the study area appeared to act as a substantial barrier to deer passage. Deer home ranges straddled highways and primary, secondary, and tertiary arterial roads. Deer crossed all types of roads. The average number of times deer crossed road during 24 hours of monitoring ranged from 2.1 to 7.0. Deer in the Los Alamos townsite avoided crossing roads during day and before sunset. Deer-vehicle accidents occurred at 350 percent of the level expected after sunset. All other time periods had fewer accidents than expected. The distribution of accidents across time periods was not similar to the distribution of road crossings across time periods for any deer. Within Los Alamos County there was a clear trend for deer-vehicle collisions to occur on roads with speed limits > 35 mph. Deer in the townsite frequently crossed roads with lower speed limits; therefore, the reason for the paucity of accidents along these roads was evidently the ability of drivers to detect deer (or the ability of deer to detect vehicles) and respond before an accident occurred. There was a significant but not strong correlation between the density of accidents and the density of road crossings. This was probably related to the high number of deer crossings of tertiary arterial roads, where accidents were not likely to occur.

Influences on farmland values in urban Texas counties and the State  

E-Print Network (OSTI)

Farmland values have been a highly researched topic for the past several decades. Interest was spurred initially by increased variability between land values and farm income during the 1950's. Prior research sought to explain value changes through the defining the relationships between land values and an assortment of farm sector and nonfarm sector variables. The foci of the prior studies were mostly rural, homogeneous areas of major agricultural states. Although Texas is considered an important agricultural state with a diversity of related enterprises, its farmland values have generally escaped the scrutiny of review. In 1992, Texas farmland comprised nearly 10 percent of the U.S. aggregated farmland value. This study sought to further knowledge by evaluating previously identified significant land value influences for their importance in Texas. Based on a literature review, proxy variables were specified to represent the influences and were tested for their explanatory ability on Texas land value data. The scope of the study was selected to reflect years that were considered historically interesting for land values in the United States, 1969 through 1994. Urban counties were studied to ascertain if identified influences were important to designated agricultural-use land near metropolitan areas. The results indicate that land supply and demand factors were the most often important influences upon land values, General agricultural economic factors were next in prevalence, followed by farm and nonfarm income factors which were not usually significant to the urban farmland. The study also emphasized that land dedicated to agricultural use in the urban counties was chiefly valued for its abilities to serve investment and consumptive purposes, instead of productive participants need to ascertain local market conditions before making a decision to buy or sell land. Land owners must carefully consider land management choices, as resource issues will increasingly impact land value. Agricultural land owners should evaluate their land primarily in terms of its investment and consumptive potential, instead of its productive qualities.

Performance limits of heliostat fields  

SciTech Connect

Geometric and thermodynamic arguments are used to derive upper limits on the performance of a solar energy collection system, consisting of an axisymmetric heliostat field, a solar tower, secondary optics and a black receiver. Performance limits on collected power, concentration, and work output are presented. Performance of tower systems with several secondary optics options is compared: tower-top Compound Parabolic Concentrator (CPC), Tailored Edge-Ray Concentrator (TERC) approximated by a cone, and Cassegrainian with ground-level CPC or Compound Elliptic Concentrator (CEC). Optimized ray tracing is used to generate the design parameters of the secondary concentrators that yield the highest optical efficiency. The results show that the tower-top Cone provides the best performance regarding both concentration and efficiency, except for very large fields. The Cassegrainian designs come in second, but become equal and even better than the Cone for large fields. The results for the Cassegrainian are sensitive to the value of the reflectivity, due to the additional reflections incurred. The choice of a CEC is better than a CPC for the terminal concentration in a Cassegrainian system, but the difference is small. The suitability of the different design options for high-temperature solar applications is discussed. The recommendations regarding optical configuration depend on field size, as well as on application-specific constraints.
