Describe processes represented by the model The primary objectives are: (1) simulation of hydrologic processes including evaporation, transpiration, runoff, infiltration, and interflow as determined by the energy and water budgets of the plant canopy, snowpack, and soil zone on the basis of distributed climate information (temperature, precipitation, and solar radiation); (2) simulation of hydrologic water budgets at the watershed scale for temporal scales ranging from days to centuries; (3) integration of PRMS with other models used for

natural-resource management or with models from other scientific disciplines; and (4) providing a modular design that allows for selection of alternative hydrologic-process algorithms from the standard PRMS module library.
