SWAT (Soil and Water Assessment Tool) has been used widely in the United States to develop total maximum daily load (TMDL) programs. As far as we know, there are no previously published studies modeling a North Carolina river with SWAT. North Carolina has 658 water bodies on the EPAs 303(d) list of impaired waters including several branches of the Haw River. The Haw River has its headwaters in the upper Piedmont physiographic region of the state and stretches 110 miles through agricultural, residential, urban and forested land, before eventually becoming part of the Cape Fear River. The objective of this project is to simulate streamflow for the upper Haw River using SWAT and the curve number technique. The chosen section of the Haw watershed covers about 1150 km2 from the headwaters to just upstream of Burlington, NC, and includes the urban sub-basin of Greensboro, NC, and the predominantly rural sub-basin to its north. Data for soils and elevation will be obtained from USDA-Natural Resources Conservation Service, for land use from USDA-National Agricultural Statistics Service, for weather from USGS-National Water Information System, NOAA-National Climatic Data Center, and the NC State Climate Office, and for reservoirs from NC Department of Natural Resources. Results of the simulation will be compared against twenty years of observed data from USGS streamflow gauges to see if SWAT could be used for watershed modeling in the North Carolina Piedmont.
