| Watershed Description: | 360 km^2 North Fork of the Upper Guadalope River, located in the Edwards Plateau region in west central Texas, U.S. |
| Calibration Summary: | 1992 - 1996: daily E = 0.4 monthly E = 0.29 |
| Validation Summary: | 1997 - Sept. 2003: daily E = 0.09 monthly E = 0.50 |
| General Comments: | SWAT was used to evaluate the influence of woody plants on water budgets of semi-arid rangeland in karst Terrain. Simulated deep percolation was considerably higher than published values. Baseline brush cover and four brush removal scenarios were evaluated. Removal of heavy brush resulted in the greatest ET (~32 mm/yr reduction over the entire basin), surface ruoff, baseflow, and deep recharge. |
