Watershed Description: | 51.3 km^2 Walnut Creek and 8.2 km^2 Buck Creek, located respectively in central and east central Iowa, U.S. |
Calibration Summary: | Monthly (1991-97): W. Creek r2 = .67 B. Creek r2 = .64 |
Validation Summary: | |
General Comments: | Simulated sediment and nitrate loads were compared between baseline land use, historical land use, and three future land use scenarios. Pollutant reductions of ~90% or more were estimated for the pre-development scenario. Large reductions were also predicted for scenarios 2 and 3. |
