| Watershed Description: | 90.23 km^2 Nagwan River, located in the Hazaribagh District in northeast India. |
| Calibration Summary: | calibrated parameters are based on values reported in Tripathi et al. (2003) |
| Validation Summary: | Monthly (1995-98) r2 values for configurations with 1, 12, or 22 subwatersheds = .86, .90, and .88 |
| General Comments: | Three different subwatershed disaggregation schemes were evaluated with SWAT for the watershed. It was found that runoff was not very sensitive to the choice of 1, 12, or 22 subwatersheds. However, marked variations are reported for ET (5 to 48%), percolation (12 to 26%) and soil water content (.3? to 22%). |
