Using a water balance model to analyze the implications of potential irrigation development in the Upper Blue Nile Basin
… understand the physical constraints, the maximum water use, and the downstream hydrological and political impacts of developing irrigation. The approach taken is to construct a physically based optimization model in the General Algebraic Modeling System (GAMS) to determine the upper bound of water …
