At a previous workshop, “Modeling Forest-Stream Interactions” (LTER All Scientists Meeting, September 1990, Estes Park, Colorado), participants discussed issues and research questions relating watershed characteristics (soils, slope, vegetation) to hillside and stream biogeochemistry, organic matter processing, and nutrient transport. Modeling the linkages among the interrelated factors clearly requires a quantitative understanding of watershed hydrology. Although several watershed hydrology models are available, few participants were familiar enough with their specific data requirements and application strengths to effectively choose among them for specific research applications.
A more technical, hands-on workshop on watershed hydrology modeling is planned for June 17-19, 1992 in Denver, Colorado to review the successes of models which have been used at several study sites, enhance current research, and facilitate further intersite collaborations.
Experts on the specific models which have particularly successful track records in ecological applications (PROSPER, PRMS, TOPMODEL) will provide instruction on model concepts, assumptions, data requirements, and hands-on testing. Model applications will be demonstrated using selected data sets and, if time permits, participants will prepare model data files from their own study sites for model applications during the workshop.
The Denver office of the U.S. Geological Survey (USGS) will provide expertise and facilities, and George Leavesley, project directory of the USGS Precipitation- Runoff Modeling Project has arranged with the National Training Center to provide classrooms and computers (Data General workstations).
