Hydrological modelling of a catchment using the SWAT model in the upper Blue Nile basin of Ethiopia

Sustaining upland agriculture and food security has been very much constrained by continuing land degradation brought by soil erosion due to lack of effective rainwater management strategies. Hydrological models are essential to understand the hydrological response of a catchment. The current paper focuses on hydrological modeling of catchment with SWAT model using its two versions, SWAT-CN and SWAT-WB. In addition, the impact of existing land and water management practices on runoff yield and the applicability of the model for the region were also addressed. The model was applied on two watersheds, Mizewa (27 km
