Abstract: A limited erosion potential analysis was carried out on the 50,000 acre School Fire. Three WEPP interfaces were used for the analysis, a GIS wizard, an online interface and a windows interface. Ten watersheds within the fire area were modeled with the GeoWEPP tool (a geo-spatial interface for WEPP, Water Erosion Predication Project). The watersheds covered 18,823 acres, or about 38 percent of the total burned area. Hillslopes were specified high, moderate or low burn severity by examining the BAER (Burned Area Emergency Response) severity map.
