| Watershed Description: | Gilgelabay, Gumara, and Ribb Rivers, which are all tributaries of the 15,321 km^2 Lake Tana drainage area (and larger Blue River Nile system) located in northwest Ethiopia (Lake Tana is the largest freshwater lake in Ethiopia and the third largest in the Nile basin). |
| Calibration Summary: | Three SWAT-MODFLOW models were setup. Each of the catchments were calibrated using daily streamflow records. The calibration results showed that statistical indices such as NSE, KGE, and PBIAS are all in the range of good to very good. |
| Validation Summary: | Similarly, the three models performed well during the calibration period. |
