Technical Abstract: The Savoy Experimental Watershed (SEW) is a University of Arkansas property of approximately 1,250 hectares (ha) in northwestern Arkansas. The SEW occurs on a mantled (regolith-covered) karst and is the site of an integrated research effort among the University of Arkansas, Arkansas Department of Environmental Quality, Agricultural Research Service of the U.S. Department of Agriculture, and the U.S. Geological Survey. As part of the integrated research effort, a long-term, interdisciplinary field laboratory will be developed for the in-situ quantitative determination of processes, controls, and hydrologic and nutrient-flux budgets in surface-water, soil-water, and shallow ground-water environments in response to specific, near-surface confined animal operation (CAFO) activities and land uses. Comprehensive research at SEW encompasses the detailed aspects of flow and solute budgets (1) from precipitation, (2) from near-surface anthropogenic activities, (3) in runoff, (4) from within the soil zone, (5) at the epikarst, (6) from within identifiable components of the shallow karst aquifer, and (7) at spring resurgences. This presentation is limited to selected elements of budget terms (5), (6), and (7) with the objective of relating areal, stratigraphic, and temporal variations in water quality to identifiable CAFO activities and to ground-water processes and controls. Current CAFO activities in basin 1 at SEW have focused on cattle and poultry.
