Dennis Flanagan is a Research Agricultural Engineer with the United States Department of Agriculture – Agricultural Research Service (USDA-ARS), stationed at the National Soil Erosion Research Laboratory (NSERL) in West Lafayette, Indiana. He is also an adjunct Professor of Agricultural and Biological Engineering at Purdue University. A lead scientist at the NSERL since 1989, his research is focused in soil erosion mechanics, erosion prediction technologies, and erosion control. His B.S. degree is from the Ohio State University, and his M.S. and Ph.D. are from Purdue University.
Dr. Flanagan has been part of the development of the Water Erosion Prediction Project (WEPP) model since 1987, and has been WEPP leader since 1999. WEPP is new generation process-based soil erosion prediction technology, designed to simulate the important physical processes driving runoff, soil erosion, and sediment loss from agricultural hillslopes, fields, and small watersheds. The WEPP model is an integral part of the Daily Erosion Project.
