Abstract: Roads can be a major source of sediment in sensitive forest watersheds. In order to economically mitigate soil erosion from roads, we need to be able to understand the processes that cause erosion. The Water Erosion Prediction Project (WEPP) has been shown to be valid for predicting erosion from some forest roads (1)(2) that can be described as hillslopes. Watershed applications of WEPP can predict erosion and sedimentation values for small watersheds (3). This paper discusses how well WEPP models insloping roads through a sensitivity analysis and validation process using two ongoing studies in the Oregon Coast Range.
