2004 Annual Report 4.What were the most significant accomplishments this past year? D. This report serves to document research conducted under a Specific Cooperative Agreement between ARS and the University of Mississippi's Department of Computer and Information Science. Additional details of research can be found in the report for the parent project 6408-13000-012-00D, Integrated Analysis of Landscape Processes for the Management of Agricultural Watersheds. Advanced watershed planning computer technology is needed by the USDA-Natural Resources Conservation Service as a tool used to develop watershed management plans. There is nothing to report for this fiscal year. Computer visualization and model distribution technology was developed for the AGNPS and CONCEPTS models. Capabilities needed by AGNPS and CONCEPTS model users were developed to visually optimize the results from complex watershed and channel system simulations. Internet WEB-based distribution technology was developed to easily transfer the models to users.
