Watershed Description: | 92.5 km^2 Nagwan River, located in the Hazaribagh District in northeast India. |
Calibration Summary: | |
Validation Summary: | Daily (June - Oct. 1997): runoff r2/E = .91/.87 sediment r2/E = .89/.89 org. N r2 = .82 org. P r2 = .86 nitrate r2 = .89 sol. P r2 = .82 ---------------------------- monthly (June - Oct. 1992-98) r2/E values: runoff = .97/.94 sediment = .92/.86 |
General Comments: | The 1997 daily flow and sediment validation results are the same as those reported in Tripathi et al. (2003). Sixty combinations of crops, tillage, and fertilizer scenarios were evaluated. The results showed that crops such as maize, peanut, and soybean generated higher sediment yields as compared to rice. The use of conventional tillage was predicted to result in the best overall sediment and nutrient losses. |
