  • Understanding the ecological effects of non-point sources of nutrient and contaminant loadings has become increasingly important in the management of riverine ecosystems, particularly since successes in controlling effluent emissions have resulted in the reduction of point-source loadings to rivers in industrialized nations. The federal governments of Canada and Germany recognize the need to evaluate the impact of non-point loading, particularly agricultural, on river systems since nutrients and agricultural contaminants can directly affect ecosystem structure and processes. Moreover, in Germany, the government`s target of achieving equal environmental conditions throughout its unified territory by the year 2000 has provided impetus to developmore » cost-effective methods for determining the effect of agricultural activity on aquatic ecosystems. The objective of this study is to combine biological, chemical and hydrological approaches for assessing non-point source loadings to rivers in Canada and the former German Democratic Republic, and to make recommendations for the design of future monitoring programs. Studies were recently initiated on small tributaries of the Elbe River, Germany, and the Athabasca River, Canada, to quantify non-point nutrient loading, identify reaches of nitrogen or phosphorus limitation, and evaluate changes in benthic algal and invertebrate communities in relation to land-use practices. Once methods have been established and validated, the project will be scaled up to large river catchment areas. This study also assesses several rapid bioassessment techniques for monitoring riverine ecosystems impacted by non-point loadings.« less
  • Systematic procedure of developing radionuclide release scenarios was established based on FEP list and Interaction Matrix for the near-surface LILW repository. The relevant FEPs were screened by experts' review in terms of domestic situation and combined into scenarios on the basis of Interaction Matrix analysis. A computer program named IMFEP{sub NS} was developed to view and select project FEPs, to make its Interaction Matrix at user's disposal, and to visualize the interaction between FEPs and Interaction Matrix. The concept of approach to generate scenarios for entire domain is to divide the whole system domain into three sections: Near-field, Far-field, andmore » Biosphere. Possible sub-scenarios were generated within each sectional subscenario set composed by assembling relevant FEPS and Interaction Matrix in advance, and then scenarios for entire system were built up with sub-scenarios of each section. As an application of established scenario generation approach, sixteen design scenarios and two alternative scenarios for near-surface repository were evaluated. Finally, a reference scenario and other noteworthy scenarios were selected through experts' scenario screening.« less
  • While the purpose of geologic storage in deep saline formations is to trap greenhouse gases underground, the potential exists for CO{sub 2} to escape from the target reservoir, migrate upward along permeable pathways, and discharge at the land surface. In this paper, we evaluate the potential for such CO{sub 2} discharges based on the analysis of natural analogs, where large releases of gas have been observed. We are particularly interested in circumstances that could generate sudden, possibly self-enhancing release events. The probability for such events may be low, but the circumstances under which they occur and the potential consequences needmore » to be evaluated in order to design appropriate site-selection and risk-management strategies. Numerical modeling of hypothetical test cases is suggested to determine critical conditions for large CO{sub 2} releases, to evaluate whether such conditions may be possible at designated storage sites, and, if applicable, to evaluate the potential impacts of such events as well as design appropriate mitigation strategies.« less
