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: | Efficiencies of the models were evaluated based on measured streamflow data.The statistical indices indicate satisfactory/above staisfactory model performances at a daily time and monthly steps, as the values of NSE, R2, and KGE were greater than 0.5 and the PBIAS values were in the range of ±25%. |
Validation Summary: | Similar to the calibration, the statistical indices (NSE, KGE, R2 > 0.5) and PBIAS ±25% values are above satisfactory. |
