Model: | SWAT |
Broad Application Category: | hydrologic only |
Primary Application Category: | HRU, subbasin, grid and/or landscape unit delineation effects |
Secondary Application Category: | input data effects |
Watershed Description: | 3.28 km^2 Animal Science and 113.4 km^2 Greenhill, located in west central Indiana, and the 22.48 km^2 Camp Shelby, located in northwest Mississippi, U.S. |
Calibration Summary: | |
Validation Summary: | Monthly (1991-95) E values reported as a function of subbasins: E =.93 to 1.0 (from 1 to 26? subbasins) --------------------------- E improved from .69 to .77 for the "Animal Science Watershed" as a function of CN calibration |
General Comments: | SWAT 94.2 was used with SWAT-GRASS to assess the effects of using different subwatershed configurations or different CN inputs on surface runoff volumes. The authors state that using virtual watersheds can adequately capture the spatial variability of watersheds. |
