The existence of the Grand Ethiopian Renaissance Dam (GERD) has a significant impact on Egypt's water share and future water usage. The filling time of the reservoir will have a great impact on the Nile River of the downstream users, especially Egypt. Many of the GERD impacts on Egypt have been previously studied, but no study has addressed the effect of the GERD existence on the hydropower water footprint of the Aswan High dam. This research is studying and simulating the effect of the different GERD reservoir filling scenarios on the water footprint of the hydropower generated from the High Aswan dam. The effect of the Aswan dam itself on the hydropower is also determined and assessed. All the assessments were carried out through Mathematical modeling. Three different filling scenarios for the GERD, namely 3 years, 5 years, and 6 years, are studied. There is a correlation observed between the length of the GERD's filling and its effect on the High Aswan dam's hydroelectric water footprint. It is found that the GERD filling time is inversely proportional to the negative impact on Aswan High dam's hydropower water footprint.
