Abstract
Soil erosion was assessed at Camp Williams Army National Guard Training Facility by creating an erosion risk classification map. The map was created by applying empirical erosion models including the Revised Universal Soil Loss Equation (RUSLE) with CIS and then grouping the quantitative erosion estimates into erosion risk classes. The assessment indicated where problem areas occurred and showed relative erosion risk, but its lack of quantitative accuracy should be noted. Soil erosion does not appear to be a problem for most of the facility except in areas with little or no protective vegetation such as roads. Analysis of each factor showed that the cover-management factor (C) contributed most of the variability to the erosion risk classification map. A comparison of three GIS derived factors (K, S, and C) to factors derived from field data indicated mixed results for accuracy.
