Model: | SWAT |
Broad Application Category: | pollutant only |
Primary Application Category: | model and/or data interface |
Secondary Application Category: | pollutant cycling/loss and transport |
Watershed Description: | 133 km^2 Big Creek, located in southern Illinois, U.S. |
Calibration Summary: | |
Validation Summary: | |
General Comments: | SWAT is interfaced with a genetic algorithm (GA) to determine optimal land use and management practices that minimize sediment loss. Several crops and three tillage levels (no, spring, & conventional) were considered in the study. Sediment output is reported for an optimized set of crops/practices for 128 subwatersheds that ranged in size from 0.29 to 4 km^2. |
