WEPP and SPUR-91 For Grassland Management in the Humid East: A Bibliography

W. E. Pitts¹, M. S. Miller-Goodman¹, and Sid Brantly²

Recent technological advancements in computerized hydrologic and water quality models have offered potentially useful ways for natural resource managers to plan and implement best management practices (BMPs) that are specific to their location and particular set of problems. In recent years, most model development relative to grassland management applications has been conducted on semi-arid or arid rangelands while development of databases for eastern grasslands and pastures has received less attention. For example, many plant characteristics that are needed to parameterize the models are not readily available for forages grown in the humid east. Currently, many of these parameters require interpretations from other measurable plant characteristics. In an effort to aid development of hydrologic and plant-related parameters for grasslands in the humid east, a bibliographic database was compiled from a variety of sources. Initial searches were performed through the Ralph B. Draughon Library, Auburn University, on twelve databases using the DIALOG search service. There were two levels of literature search and acquisition:

• An attempt was made to find all literature directly related to modeling using WEPP and SPUR-91 on pasture and grassland in sub-humid areas.
• Literature that relates to other parameters required by the models was also cataloged. These included articles that contain information relative to nutrient loss, surface runoff, and erosion from humid region grasslands.
