However, many of the management options focus on components of the watershed at different spatial scales such as upland areas, riparian areas, and instream processes swhile others focus on watershed-scale issues such as water supply and quality, sediment yield, rangeland health, and sustainable yield of watershed resources. To evaluate the alternative management options, hydrologic models are needed to simulate the hydrologic cycle on watersheds and to provide information on processes and states of the system across a range of spatial and temporal scales. Gaps in information and knowledge limiting our ability to develop and implement appropriate hydrologic models at the watershed scale are identified and general research programs needed to address these problems are specified. Hydrologic databases and knowledge bases from case studies are used with distributed simulation models to define specific research projects needed to generate new information and knowledge prerequisite to simulation of dominant processes determining watershed response across a range of temporal and spatial scales. |
