Major Sedimentation Activities in the Soil Conservation Serviceby Charles D. Clarke, Soil Conservation Service, Washington, United States,
Abstract: The Agricultural Research Service (ARS) and Soil Conservation Service (SCS) are cooperating in the development of tools to improve prediction of the magnitude of erosion processes, the quality and amount of sediment leaving fields, and the effectiveness of various conservation practices. A major purpose of these tools is to prioritize sediment source areas for treatment and to select appropriate practices. They would also provide for improved assessment of erosion and sedimentation conditions Nationwide. This paper is restricted to discussion of three math models. They are the Water Erosion Prediction Project (WEPP), the Ephemeral Gully Erosion Model (EGEM), and the Hydrogeomorphic Sediment Yield Model (HUSLE).
