Watershed Description:
fiogf49gjkf0d
973 ha Kapgari (West Bengal state in eastern India) 
Calibration Summary:
fiogf49gjkf0d
Daily 2002 (rainy season) runoff r2 & E = .94 & .88 sediment r2 & E = .93 & .84 nitrate r2 & E = .93 & .92 total P r2 & E = .92 & .83 
Validation Summary:Daily 2003 (rainy season) runoff r2 & E = .91 & .85 sediment r2 & E = .89 & .86 nitrate r2 & E = .87 & .83 total P r2 & E = .94 & .89 
General Comments:SWAT was applied to the Kapgari watershed during May-Oct. (rainy season) during 2002-2003. Crops simulated were rice, peanut, and maize. The impacts on runoff and pollutant losses are reported for 48 different crop, tillage & fertilizer combination scenarios. It was concluded that rice cannot be replaced by other crops during the rainy season in order to minimize sediment and nutrient losses, and that a lower rates of N & P fertilizer (80/60 N/P vs. 120/80 N/P kg/ha) could be used because rice yields were maintained and nutirent (nitrate & P) pollution was reduced.
