| 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): runoff r2/E = .76/.71 sediment r2/E =.54/.-67 |
| Validation Summary: | Daily (1981-83; 1985-89; 1991): runoff r2/E = .83/.54 sediment r2/E =.65/.70 |
| General Comments: | The watershed is located in the "second most seriously eroded region in the world." SWAT was able to realisticall replicate measured runoff and sediment losses, and thus was found to be a ver viable tool for determining priority subwatersheds in the watershed. An alternative "subjective evaluation approach" was also used to assess sediment losses in the watershed but was found to be unreliable. |
