Modeling soil loss to determine water erosion risk at Camp Williams National Guard Base, Utah

Soil erosion was assessed at Camp Williams by creating an erosion risk classification map and comparing the erosion impact of disturbance regimes on different hillslopes.; The Revised Universal Soil Loss Equation was applied using GIS to create a soil erosion risk map for the entire facility. Soil erosion did not appear to be a problem for most of Camp Williams. Areas of concern included landscapes with little or no protective vegetation.; The Water Erosion Prediction Project model was used to evaluate the erosion impacts of various disturbances on five study hillslopes. The model did not appear to function well because the distribution of infiltration rates could not be satisfactorily represented.; Erosion bridges were also used on the study hillslopes in an attempt to measure soil loss and deposition. However, the bridges lacked the capability of measuring erosion at the low rates occurring during the time period set for this experiment.
