Multi-purpose Reservoir Operation Analysis in the Blue Nile Basin, Ethiopia

This study focused on developing rule curves for multi-purpose cascade reservoirs operation to optimize the available water for hydropower production, irrigation development, water supply, and environmental flow in Blue Nile Basin using HEC-ResSim reservoir simulation model. The model tried to represent the physical behavior of cascade reservoirs in the basin with its high speed hydraulic computations for flows through control structures, and hydrologic routing to represent the lag and attenuation of flows through the main and tributaries of the river based on the current projects operation, and future likely development projects implementation period. Therefore, the management of multi-purpose cascade reservoirs is complex due to conflicting interests between these objectives. Thus, the optimal operation of cascade reservoirs is important to address trade-offs between multiple objectives to achieve the water management goals. From the simulation of cascade reservoirs operation, Hydropower power guide curve operation rule was selected to optimize the basin’s available water.
