The construction of the Grand Ethiopian Renaissance Dam (GERD) on the Nile River, alongside the existing High Aswan Dam (HAD), creates a complex transboundary water situation. This paper simulates the GERD's filling period, a new normal post-filling, and a severe multi-year drought to analyze potential risks and opportunities for Egypt, Sudan, and Ethiopia. The analysis shows minimal water shortage risk for Egypt during filling, benefits for Ethiopia and Sudan in the new normal, and the critical need for coordinated drought management to minimize harmful impacts.
