| Watershed Description: | 95.76 km^2 Nagwan River, located in the Hazaribagh District in northeast India. |
| Calibration Summary: | Daily (1984 & 1992: highest & lowest water & sediment years): sediment r2/E = .54/-.67 |
| Validation Summary: | Daily (1981-83; 1985-89; 1991): sediment r2/E = .65/.70 |
| General Comments: | SWAT was interfaced with an LP model within a spatial decision support system to evaluate land use scenario effects on sediment loss. An optimized LP-based land use plan resulted in a redistribution of paddy, corn, and forest land use (but no change in the total areas of each) that resulted in a sediment yield decrease of ~15%, and increases in rice paddy and corn productivities of ~3 and 68%, respectively. Daily time step for calibration & validation is not mentioned in the paper, but is assumed based on identical statistics reported in other Kaur et al. 2004. |
