Broad Application Category:hydrologic and pollutant 
Primary Application Category:tile drainage effects and/or processes 
Secondary Application Category:depressional (pothole, wetland or pond) effects and/or processes 
Watershed Description:51.3 km^2 Walnut Creek, a tributary of the Skunk River located southeast of the City of Ames in Story County in central Iowa, U.S. 
Calibration Summary:Monthly (1991-98) at watershed outlet: streamflow r2 = .73 nitrate r2 = .56 
Validation Summary: 
General Comments:SWAT streamflow and nitrate discharge at the watershed outlet was found to be in accordance with observed data. Seven N fertilizer scenarios (% deviations from 152 kg/ha N reference rate) and lanuse scenarios, including winter wheat replacing corn-soybean and fertilized pasture scenarios, were performed. Decreasing N rates by 20, 40, & 60% in corn-soybean fields reduced N losses by 22, 50, & 95%.
