| Watershed Description: | 51 km^2 Maarkebeek, 114 km^2 Zwalm and 204 km^2 Aa Rivers, which are subwatersheds of the Scheidt River located in northern Belgium. |
| Calibration Summary: | graphical E values presented ≈ .7 - .9 |
| Validation Summary: | graphical E values presented ≈ .6 - .8 |
| General Comments: | The validity of 7 ket SWAT hydrologic parameters was tested by transferring them within a watershed, to a neighboring watershed, and to a watershed with different environmental characteristics. The results showed a decline in model performance when parameters were transferred in time and space. Reasonable performance was found for transfers within a watershed and to a neighboring watershed. The authors state that caution should be used for transferring parameters between regions with different topography, land use, and soils. |
