Online Web Tool for Soil Erosion Prediction The Water Erosion
Prediction Project (WEPP), in the Soil and Water Engineering
group at the Moscow Forest Sciences Laboratory, uses a number of
specialized tools for roads, managed forests, and forests
following wildfire to predict soil erosion. The daily climate
parameter inputs into these predictive tools can be readily
altered to reflect warmer or colder, and wetter or drier
climates, by month. Our erosion model is physically-based. WEPP
includes vegetation growth algorithms which are dependent on
soil water availability and daily temperatures. Our predictive
tools can thus show the interactions among climate, plant
growth, and erosion. This means a drier and/or hotter climate
may result in less vegetation, leading to either increased
erosion because of reduced ground cover, or reduced erosion
because of reduced precipitation. Because WEPP is driven by both
temperature and precipitation, it can show the effects of
changing climate on snow accumulation, melt, and
