| Model: | SWAT |
| Broad Application Category: | hydrologic only |
| Primary Application Category: | snowmelt, frozen soil and/or glacier melt processes |
| Secondary Application Category: | hydrologic assessment |
| Watershed Description: | 4,999 km^2 Wind River (West central Wyoming) |
| Calibration Summary: | |
| Validation Summary: | Annual (1991-96) average E = 0.86 (after adjustment); initial version of routine = -0.70 |
| General Comments: | Initial evaluation indicated that SWAT could not accurately simulate snowmelt processes for the mountainous watershed. Algorithms were then developed that distribute temperature & precipitation as a function of elevation bandsand account for snow? temperature, meltwater production, and areal snow coverage. Improved results were found with the new algorithms, with the E statistic increasing from -0.70 to 0.86 after the changes. |
