Enhancing transboundary flood forecasting for early warnings in the Gash River Basin by Amarnath, Giriraj, Alahacoon, Niranga, Gismalla, Y., Mohammed, Y., Sharma, Bharat R., Smakhtin, Vladimir

“…Hydrological modeling of large river catchments has become a challenging task for water resources engineers due to the complexity of collecting and handling both spatial and nonspatial data, such as rainfall, gauge-discharge data, and topographic and hydraulic parameters. The Gash is a transboundary river which originates from the Eritrean Highlands and Ethiopian Plateau and ends up in Sudan. …”

Watershed modeling for reducing future non-point source sediment and phosphorus load in the Lake Tana Basin, Ethiopia by Moges, M.A., Schmitter, Petra S., Tilahun, Seifu A., Steenhuis, Tammo S.

“…The model parameter based prediction of source areas for the non-point source sediment and P was also evaluated spatially and compared with the Topographic Wetness Index (TWI) of the watershed. Results and discussion - The water balance component of the non-point source model performed well in predicting discharge, sediment, DP, and PP with NSE of 0.7, 0.65, 0.65, and 0.63, respectively. …”
