  • Understanding the response of river flow and estuarine hydrodynamics to climate change, land-use/land-cover change (LULC), and sea-level rise is essential to managing water resources and stress on living organisms under these changing conditions. This paper presents a modeling study using a watershed hydrology model and an estuarine hydrodynamic model, in a one-way coupling, to investigate the estuarine hydrodynamic response to sea-level rise and change in river flow due to the effect of future climate and LULC changes in the Snohomish River estuary, Washington, USA. A set of hydrodynamic variables, including salinity intrusion points, average water depth, and salinity of themore » inundated area, were used to quantify the estuarine response to river flow and sea-level rise. Model results suggest that salinity intrusion points in the Snohomish River estuary and the average salinity of the inundated areas are a nonlinear function of river flow, although the average water depth in the inundated area is approximately linear with river flow. Future climate changes will shift salinity intrusion points further upstream under low flow conditions and further downstream under high flow conditions. In contrast, under the future LULC change scenario, the salinity intrusion point will shift downstream under both low and high flow conditions, compared to present conditions. The model results also suggest that the average water depth in the inundated areas increases linearly with sea-level rise but at a slower rate, and the average salinity in the inundated areas increases linearly with sea-level rise; however, the response of salinity intrusion points in the river to sea-level rise is strongly nonlinear.« less
  • Future climate simulations based on the Intergovernmental Panel on Climate Change emissions scenario (A1B) have shown that the Skagit River flow will be affected, which may lead to modification of the estuarine hydrodynamics. There is considerable uncertainty, however, about the extent and magnitude of resulting change, given accompanying sea level rise and site-specific complexities with multiple interconnected basins. To help quantify the future hydrodynamic response, we developed a three dimensional model of the Skagit River estuary using the Finite Volume Coastal Ocean Model (FVCOM). The model was set up with localized high-resolution grids in Skagit and Padilla Bay sub-basins withinmore » the intermediate-scale FVCOM based model of the Salish Sea (greater Puget Sound and Georgia Basin). Future changes to salinity and annual transport through the basin were examined. The results confirmed the existence of a residual estuarine flow that enters Skagit Bay from Saratoga Passage to the south and exits through Deception Pass. Freshwater from the Skagit River is transported out in the surface layers primarily through Deception Pass and Saratoga Passage, and only a small fraction (≈4%) is transported to Padilla Bay. The moderate future perturbations of A1B emissions, corresponding river flow, and sea level rise of 0.48 m examined here result only in small incremental changes to salinity structure and inter-basin freshwater distribution and transport. An increase in salinity of ~1 ppt in the near-shore environment and a salinity intrusion of approximately 3 km further upstream is predicted in Skagit River, well downstream of the drinking water intakes.« less
  • In North Carolina, small coastal plain estuaries incised into the mainland have received little investigative focus compared to fronting bar-built systems. Accelerating population growth prompted a county-wide survey for purposes of regional land use planning. Hewlett's Creek, a tide-dominated estuary and the largest of these systems in New Hanover County (15 km[sup 2]), was selected as an exemplary site for detailed study. Twenty-five vibracores were recovered from a 4km[sup 2] area dominated by Spartine alterniflora marshes. Seventy-five surface samples provide data on diagnostic parameters of subenvironments. Radiocarbon dated shells and peat suggest initial flooding of deeper parts of the systemmore » occurred 5,300 years B.P. and by 4,500 years B.P. flooding was complete. The innundated irregular low-relief Pleistocene surface consists of humic-stained quartz sands and iron-stained compact silty clays exposed in low-relief scarps on the estuary margins. Fill thickness exceeds 8m in the paleo-channels. Unlike the adjacent Masonboro bar-built system, appreciable thicknesses of mud are common, particularly in the upper reaches where 2--4m of mud has accumulated. Portions of the upper system are capped by 2m thick Spartina peats which reflect uninterrupted marsh production and anomalous peat accumulation for the past 4,200 years. Dredging of the Intracoastal Waterway in 1930 apparently altered hydrodynamics and associated sedimentation patterns within the lower portions of the estuary. Aerial photographs document increased shoaling and a marked increase in tidal marsh are near the mouth. The wedge of sandy sediments characteristic of this area is overlapping the mud-dominated western portion where the upper 6m of fines is mostly organic-rich muds. One km west of the junction with the Waterway an abrupt decrease in the distribution and abundance of sand and oyster flats separates the sand-rich portion from the mud-dominated portion.« less
  • Simulations with General Circulation Models have indicated that global warming will be enhanced at high latitudes. Regions in the high Arctic are highly sensitive to increased concentrations of greenhouse gases, with an amplified theoretical rise of 8--14 C predicted to take place in winter and a negligible rise of 2 C in summer. Wetter conditions in these regions are quite plausible with global warming due to warmer sea surface temperatures, melting of sea ice and a greater moisture holding capacity of the atmosphere. Recent observations show a marked increase in precipitation in the high Arctic regions during the past decades,more » particularly in the winters. The notion of whether the increased melting of snow due to global warming would be offset by increased snowfall is investigated in this study. To make reliable predictions of the response of high Arctic glaciers to global warming and hence their contribution to sea-level rise, a numerical model has been developed to investigate the interactions of the glaciers with climate change induced by global warming. The model is a one-dimensional numerical ice-flow model coupled with a surface balance model. Accumulation and ablation at the glacier surface are determined by the surface balance model using an energy balance approach.« less
  • State coastal zone management programs are responding to the potential impacts of accelerated sea level rise through a wide range of activities and policies. The federal Coastal Zone Management Program (CZMP) responses to concerns about accelerated eustatic sea level rise were classified into four categories: official recognition and assessment of problems and issues; new public and intergovernmental processes; existing adaptable legislation; and new policies responding to sea level rise. Of 24 marine coastal states, 16 were credited with formal recognition of the problem, while only 3 have implemented new policies addressing the issue. Alternative policy responses to sea level risemore » included zoning restrictions, economic incentives/disincentives, prohibitions or restrictions on development, nonstructural engineering, and groundwater protection policies. Linking sea level rise to more immediate and tangible issues, such as coastal erosion, storm protection, public recreation, and access, provides an opportunity for CZMPs to increase their role in coastal land use policy. Programs that are able to incorporate sea level rise considerations into their overall program objectives will succeed in broadening the scope and range of the planning process. 119 refs., 2 tabs.« less
