Summary
Modeling of watershed response to normal and extreme climatic conditions or to changes in the physical conditions of a watershed requires the simulation of a variety of complex hydrologic processes and process interactions. Some of these processes are well understood at a point or for a small area; others are poorly understood at all scales. Increasing spatial and temporal variability in climate and watershed characteristics with an increase in watershed area adds significantly to the degree of difficulty in investigating and understanding these processes. Research is needed to better define these processes and to develop techniques to simulate these processes and their interactions at all watershed scales. Project objectives are to investigate watershed hydrologic processes and processes interactions to (1) Improve understanding of watershed system dynamic; (2) develop computer models to simulate and evaluate the effects of various combinations of precipitation, climate, and land use on streamflow, sediment yield, and other hydrologic components; and (3) develop procedures and techniques to estimate model parameters using measurable watershed and climatic characteristics. A GIS grapical-user-interface to be used in watershed modeling. for the development of Parameter Inputs for Watershed Modeling, and the Modular Modeling System, a framework which allows the model user to selectively couple to selectively couple the most appropriate process algorithms from applicable models to create an "optimal" model, see project's home page.
