The Water Erosion Prediction Project (WEPP) model is a process-based, continuous simulation, distributed parameter, hydrologic and soil erosion prediction system. It has been developed over the past 25 years to allow for easy application to a large number of land management scenarios. Most general or field agency users of WEPP rely upon existing or special databases and/or interfaces that have been developed, tested, and verified by others. This article describes WEPP model calibration and validation procedures, under ideal situations (where all necessary input data and runoff/sediment observations are available) as well as under more typical and less ideal conditions. Two case study applications of the model from the literature are highlighted and discussed in detail as examples of single storm hillslope profile and continuous simulation watershed applications. Current and future development efforts on WEPP are also described.(Download PDF) (Export to EndNotes)
