Water Erosion Prediction Project (Wepp): Development History, Model Capabilities, And Future Enhancements, Dennis C. Flanagan, John E. Gilley, Thomas G. Franti
Water Erosion Prediction Project (Wepp): Development History, Model Capabilities, And Future Enhancements, Dennis C. Flanagan, John E. Gilley, Thomas G. Franti
Biological Systems Engineering: Papers and Publications
The Water Erosion Prediction Project (WEPP) was initiated in August 1985 to develop new‐generation water erosion prediction technology for use by federal action agencies involved in soil and water conservation and environmental planning and assessment. Developed by the USDA‐ARS as a replacement for empirically based erosion prediction technologies, the WEPP model simulates many of the physical processes important in soil erosion, including infiltration, runoff, raindrop and flow detachment, sediment transport, deposition, plant growth, and residue decomposition. The WEPP project included an extensive field experimental program conducted on cropland, rangeland, and disturbed forest sites to obtain data required to parameterize and …
Early Investment In Soil Conservation Research Continues To Provide Dividends, John E. Gilley, D. C. Flanagan
Early Investment In Soil Conservation Research Continues To Provide Dividends, John E. Gilley, D. C. Flanagan
Biological Systems Engineering: Papers and Publications
Current soil conservation programs are built upon an established research legacy. Hugh H. Bennett, chief of the USDA Soil Conservation Service from 1935 to 1951, was instrumental in the establishment of a network of 35 soil conservation experiment stations (SCES). Research projects were initiated at the SCES in the 1930s to investigate the principal factors causing erosion and to identify the most effective and practical methods of controlling soil loss from agricultural areas. Information obtained from the SCES, and selected other locations, was assembled at the National Runoff and Soil Loss Data Center (NRSLDC) established on the campus of Purdue …
Sediment Movement Within A Strip Intercropping System, John E. Gilley, L. A. Kramer, R. M. Cruse, A. Hull
Sediment Movement Within A Strip Intercropping System, John E. Gilley, L. A. Kramer, R. M. Cruse, A. Hull
Biological Systems Engineering: Papers and Publications
This study was conducted to identify sediment movement within a strip intercropping system in southwestern Iowa during the third year of a three-year crop rotation. Soil loss, resulting from the application of simulated rainfall to a Monona silt loam soil, was measured from individual corn (Zea mays L.), soybean (Glycine max (L.) Merr), and winter wheat (Triticum aestivum L.) strips, and from multiple strips which included all three crops. Because of the crop rotation and residue management procedures, used at the study site, a substantial amount of surface cover and vegetative mass was present on each of …
Tillage Effects On Soil Erosion Potential And Soil Quality Of A Former Conservation Reserve Program Site, John E. Gilley, J. W. Doran
Tillage Effects On Soil Erosion Potential And Soil Quality Of A Former Conservation Reserve Program Site, John E. Gilley, J. W. Doran
Biological Systems Engineering: Papers and Publications
This study was conducted to determine the effects of tillage on soil erosion potential and soil quality characteristics of a former Conservation Research Program (CRP) site. Following tillage, the study area in northern Mississippi was maintained in a fallow condition for nine months. Soil loss from simulated rainfall events was minimal on recently tilled plots and an adjoining, undisturbed CRP area. In contrast, soil loss from the former CRP site which had been tilled nine months previously was similar to values obtained before the CRP program when the area had been cropped for several years. Tillage and over-winter fallowing caused …
