Egypt will need an additional 21 billion cubic metres of water per year by 2050

Reduction in demand for hydroelectric power through development of wind and solar could provide some of that additional water, especially at times of low flow, as more water would be available given the same input from up stream. Another possibility would be any effective measure to reduce silting behind the dam, (which will be reduced by an upstream dam).
