Just over 50 years ago, predicting soil erosion was a time-consuming manual process. These methods have evolved over time and now include models such as the Water Erosion Prediction Project (WEPP), which helps simulate the important physical processes that result in soil erosion by water. It was the goal of this study to build on the WEPP model to create a multi-scale software tool that could provide fire and fuel managers with access to the geographic data and detailed images they needed to predict soil erosion after wildfire and fuel-reduction treatments. The new tool, known as the Geo-spatial interface for WEPP (GeoWEPP), digitally enhances WEPP simulations by linking with Geographic Information Systems (GIS) and tapping into digital sources of information such as digital elevation models and topographic maps. With GeoWEPP, fire manag
