Water Erosion Prediction Project (WEPP) Technology for Assessment of Runoff, Soil Loss and Sediment Yield Potential

The Water Erosion Prediction Project (WEPP) model is a process-based, distributed parameter,continuous simulation computer program for estimation of runoff, soil loss and sediment yield from fields andsmall watersheds. In addition to having large databases for application to a multitude of U.S. soils, climatesand management systems, WEPP also has a variety of user interfaces that make use of the model very easy.For many users, very simple and rapid erosion estimates can be made with web-based versions of WEPP,accessible through the National Soil Erosion Research Laboratory's (NSERL) web servers. For more detailedand focused conservation planning or erosion inventories, there is a stand-alone Windows interface as well asan Arc-View GIS extension (GeoWEPP). Erosion science technology within the current WEPP model is beingextracted and ported into a new combined wind and water erosion process model being developed under theObject Modeling System (OMS) in cooperation with USDA scientists in Fort Collins, Colorado, Manhattan,Kansas, and at other locations in the United States.
