Are we using the right fuel to drive hydrological models? A climate impact study in the Upper Blue Nile

Stefan Liersch et al.

Data sets

Discharge simulations for the Blue Nile at gauge El Diem based on uncorrected and bias-corrected GCM and RCM inputs Stefan Liersch

Bias-corrected CORDEX precipitation, min/mean/max temperature for Ethiopia, RCP 4.5 and RCP 8.5 S. Liersch, H. Rust, A. Dobler, T. Kruschke, and M. Fischer

Short summary
Application-oriented regional impact studies require accurate simulations of future climate variables and water availability. We analyse the quality of global and regional climate projections and discuss potentials of correction methods that partly overcome this quality issue. The model ensemble used in this study projects increasing average annual discharges and a shift in seasonal patterns, with decreasing discharges in June and July and increasing discharges from August to November.
