ABSTRACT
In this chapter, the implications of water resources development in the Eastern Nile basin on water availability for hydropower generation and irrigation demands were assessed at country and regional levels, using scenario analysis methods. In this chapter, the Eastern Nile water resources development options are quantitatively analysed, based on the recent plans for dam and irrigation development, considering different management options. RIBASIM simulates the performance of a system using hydrologic time series and allocation rules. Two Eastern Nile models have been developed, one based on cooperative transboundary operation of all dams in the basin, and one where countries operate the dams unilaterally. In the cooperative transboundary management scenarios, all water users are connected to one or more upstream sources depending on the network links. The model provides quantitative information to understand the consequences of the available plans of dam development and agricultural expansion in the basin.
