WEPPCAT: The Water Erosion Prediction Project Climate Assessment Tool

Guest Post by Timothy Bayley
The WEPPCAT is a web-based extension of the Water Erosion Prediction Project (WEPP). WEPPCAT allows users to model the effect that climate changes could have on soil erosion rates given user defined climate scenarios. Users are able to change rainfall intensity, total precipitation, number of wet days, and temperature highs and lows. WEPPCAT is the first model to allow easy manipulation of the intensity or volume of rain falling in individual storm events. In addition, WEPPCAT allows people to identify the optimal filter strip width for modified climate conditions using the filter strip assessment tool. The WEPPCAT model is recommended for use by land managers, farmers, planners, conservationists and teachers. The model is available in a web-based format accessible for free at Tutorials and scientific references are also available on the Web site.
