Egypt relies on the Nile River to meet its increasing demands. Therefore, it is necessary to predict the change in water supply from Nile River due to climate change phenomenon. The impacts of climate change should be considered not only on the national level but also on the governorate level, because the water resources systems in the Egyptian governorates have different characteristics. Hence, the main objective of this study was to investigate climate change impacts on water resources systems in the Egyptian governorates and to set up necessary adaptation measures. The specific objectives were to: predict the expected releases from Aswan High Dam (AHD) due to climate change using BlueM model, study the influence of flow changes on water balances of the Egyptian governorates using a Water Balance Model (WB Model) developed by the authors, and conduct sensitivity analyses of adaptation measures to reduce the expected water shortages. Three governorates were selected namely; Qena to represent Upper Egypt, Fayoum to represent Middle Egypt and Damietta to represent Lower Egypt. The results showed that the expected release from AHD in 2050 will be reduced to 93.2 % and 84.7% of the current release based on two different emission scenarios. Consequently, the WB Model showed that Fayoum was the most affected governorate, whereas its water shortage increased in 2050 for the two scenarios. The ratio of drainage reuse to total water supply also increased for the two scenarios, and nevertheless, the drainage water did not fully cover the shortage. Moreover, no drainage was discharged to Quarun and Wadi El Rayan lakes at the system end threatening their existence. Damietta would be under high risk of severe water pollution in case of reduced release, since the ratio of drainage reuse to total supply severely increased. The sensitivity analysis proved that modern irrigation systems in the new lands, land leveling, controlling rice and sugarcane areas, and lining the reaches of irrigation canals characterized by excessive losses would lead to minimizing the future water shortage and subsequently minimizing the drainage reuse. less
