Fred Theurer, Agricultural Engineer

  • Tel: 301-504-3962

Fred has been involved with agricultural watershed engineering since well before the Soil Conservation Service changed names and became NRCS. He graduated from the University of Maryland in 1959 with a B.S. in Civil Engineering. During his junior and senior years he worked for the Maryland Work Plan Party under the tutelage of the state Hydraulic Engineer. Upon graduation and, after a short stint with the California Department of Water Resources, he joined SCS in 1960 and has been with us ever since. Fred completed his Masters in Stream Mechanics at Colorado State University in 1974, and his Ph.D. in Hydraulics at that same institution in 1975. In addition to fourteen years of engineering and watershed planning work experience, more than six years were spent as the Head of the ADP Unit at the Northeast National Technical Center (NNTC). The position included complete responsibility for all computer program and related model development for the NNTC region. Several model-related computer programs were developed during this period. The years since graduate school have been spent working in an inter-institutional environment on computer model development. In addition to sometimes having to work alone, the development efforts more often required working with other scientists including soil scientists, engineers, biologists, and economists. The model development included working with the USDA-Agricultural Research Service (ARS), USDA-Forest Service, USDI- Fish & Wildlife Service, USDI-Geological Survey, USDI-Bureau of Land Management, and USDI-Bureau of Reclamation. Currently serving as the NRCS AGNPS Project Manager of a multi-agency (NRCS & ARS) & multi-disciplinary (engineers, agronomists, geologists, soil scientists, & other disciplines) team which has converted the ARS single-event AGNPS (AGricultural Non-Point Source Pollution) computer model into the continuous simulation model AnnAGNPS (Annualized AGNPS) and, in addition to the development of many new features for AnnAGNPS, has developed or assisted with the development of several other models that have been included into a suite of environmental-related computer models for AGNPS. AnnAGNPS is designed to be used for risk analysis of the effects of conservation practices on surface runoff loadings (water, sediment, nutrients, & pesticides).
