Project Summary

This project parameterized the Watershed Erosion Prediction Project (WEPP) model, improved the WEPP: Road interface, and validated the WEPP model for the Lake Tahoe Basin. The project also developed a GIS-based quantitative approach to predict sediment loading using WEPP: Road, identified erosional “hot spots” from a watershed-scale road network, and determined the optimal road network design that minimizes sediment production through best management practice (BMP) application.
