Abstract: The X-DRAIN model is a user-friendly computer program based on the Water Erosion Prediction Project (WEPP) and is designed to estimate sediment yield from roads, landings, skid trails, and foot trails as affected by climate, soil, local topography, and transportation system characteristics. X-DRAIN can be used to determine optimum cross drain spacing for existing or planned roads, and for developing and supporting recommendations concerning road construction, reconstruction, realignment, closure, obliteration, or mitigation efforts based on sediment yield. The model estimates sediment yield produced by a given road or road system by summing sediment quantities from each unique road segment or road length between cross drains.
This report provides a brief background of WEPP, discusses applications of X-DRAIN, and details examples to assist the field user with software implementation. Appendix A contains instructions for installing this application on the PC. Included are hardware requirements, application features, and removal of the application from the PC. Other appendices provide background information useful for proper application of the model.
