| Broad Application Category: | hydrologic only |
| Primary Application Category: | groundwater and/or soil water impacts/processes |
| Secondary Application Category: | hydrologic assessment |
| Watershed Description: | 258 randomly slected locations within 258 0.25x0.25ยบ cells covering the entire state of Oklahoma, U.S. |
| Calibration Summary: | |
| Validation Summary: | daily comparisons at two sites for soil moisture: Person's r and coefficient of efficiency statistics reported |
| General Comments: | SWAT was ued to document 30-year (1962-91) long-term average soil moisture conditions and variability, & topsoil variability. The model was judged to be able to accurately estimate the relative magnitude and variability of soil moisture in the study region. The soils were found to be generally about 70% of field capacity in winter & spring and about 30% in summer; graphical results are also shown. |
