Technical Abstract: WEPP is a computer model for predicting soil erosion and sediment delivery from fields, farms, forests, rangelands, construction sites and urban areas. It embodies the fundamental concept that erosion was a process of detachment and transport. Soil erosion is modeled as rill and interrill erosion processes. The sediment delivery is modeled in the watershed routines in WEPP with channels and impoundments on and leading from fields. The watershed routines estimate detachment and deposition in channels and impoundments. Channels may include grassed waterways, other small channels on fields, or road ditches. Impoundments may be small reservoirs, impoundment terraces, small pondage areas above culverts, or water ponded above silt fences or straw bales. WEPP is available on the internet, and is supported by a maintenance team. Efforts are underway to produce a comprehensive interface that will meet users needs. Additionally, WEPP has been thoroughly tested on plots and watersheds, and is being implemented by the U.S. Forest Service. Future efforts will be directed toward further implementation, commonality of interfaces and science with other ARS erosion models, and enhancements as needed.
