There is a high demand for Geographic Information System (GIS) tools or interfaces to estimate
the impact of Best Management Practices (BMPs) for large watersheds. The Water Erosion
Prediction Project (WEPP) DOS executable had been validated for several plots and watershed
sites in the US. The latest WEPP Windows version – using the very same DOS executable -
offers a user-friendly interface to implement the latest site-specific BMP in detail. After
validating the WEPP Windows interface for the original validation sites for the first time, we
systematically implemented two BMPs - field border and grassed waterway - to observe the
potential impact on soil loss, runoff and sediment yields at these validation sites.
