| Broad Application Category: | hydrologic only |
| Primary Application Category: | climate change |
| Secondary Application Category: | Hyrologic Unit Model of the U.S. (HUMUS) application |
| Watershed Description: | 18 Major Water Resource Regions (MWRRs), which comprise the conterminous U.S. |
| Calibration Summary: | |
| Validation Summary: | average annual overall water yields at WRR outlets (1961-1990): r2 = .92 ---------------------------- individual WRR water yields average across 8-digit watersheds (1961-1990): r2 = .03 to .90 |
| General Comments: | SWAT (within HUMUS) was driven with GCM (HadCM2) climate projections for 2030 and 2095, and compared to a baseline of 1961-90. Changes in predicted hydrologic balance (PET, ET, surface runoff, and water yield) are shown using maps of the U.S. and regional charts. Greater precipitation was predicted for 2090 relative to the baseline and 2030 for most regions, resulting in corresponding greater water yields. |
