Abstract
The Water Erosion Prediction Project Climate Assessment Tool (WEPPCAT) was developed to be an easy-to-use, web-based erosion model that allows users to adjust climate inputs for user-specified climate scenarios. WEPPCAT allows the user to modify monthly mean climate parameters, including maximum and minimum temperatures, number of wet days, precipitation, and precipitation intensity (change in heavy precipitation events) in order to assess changes in surface runoff and soil erosion. In addition, the model allows the user to assess the impacts of a variety of land management alternatives including riparian filter strips. An important aspect of the tool is that databases for the model are pre-constructed; therefore, it does not require specialized scientific expertise to run, and scenarios are quick and easy to set up. This paper presents the conceptual and technical basis for WEPPCAT, and an example application is given for sediment delivery on a transect running north-south from Minnesota to Louisiana under several climate change scenarios.
