FTA: This is further expedited by the threat of rising sea levels and climate change
Maybe they could release a lot of water from time to time to fix the various issues. Any article that uses “Sustainability” and climate change and says the sea is rising is not to believed.
The water level of Lake Nasser had been in decline for years, last I checked (which was a while back). My approach would be to install a huge version of a pool cover, which is made of that pucker-pack stuff used to ship fragile items. The higher the water level, the more electricity the dam can generate with the same amount of water, which further enhances the ability of the Nile to maintain that water level, etc etc.
