Abstract

This paper predicts impact of sea level rise (SLR) on the micro-hydropower generation from Idfina barrage and submits a proposal to adapt the negative effect. Idfina barrage was constructed on Rosetta Branch. It is located 18 km far from the Mediterranean Sea, which reserves the sea water to overcome to the Nile River. Three scenarios referred to the discharge, net head and turbine’s level are suggested, taking into consideration cases studies of SLR; (1) Pessimistic case, that consider the sea water level change according to (IPCC) plus the subsidence value, according to CoRI1 (Study1 in Coastal Research institute, CORI), which means SLR is expecting maximum rises. (2) Normal case; which is the base situation, which mean the actual measurements of SLR according to CoRI2 (study2 in CoRI) are used. (3) The optimistic case, which is the sea water level rise referred to (IPCC) only, which means SLR is minimum. Mathematical model is used to determine the different impacts of the sea level rise on the electric generation. Analyzing different levels of turbine is taken place to adapt the negative impact of SLR. Results concluded that; all cases of SLR have adversely impact on the hydropower generation. Reduction in generated power without adaptation in maximum and minimum sea level for scenarios with cases; pessimistic and optimistic are recorded 54% and 29%, respectively. Reduction in generated power with adaptation in maximum and minimum sea level for scenarios with cases; pessimistic and optimistic are decreased to 43 % and 15%, respectively.
