The DWEC presents a promising and practical approach for transboundary river basin cooperation, and it can potentially be applied in other river basins. For example, with the construction and operation of the upstream Grand Ethiopian Renaissance Dam and downstream High Aswan Dam, riparian countries in...
To be able to produce electricity, the water from the reservoir must travel through the dam. Power plant operators use a sluice gate, or a controllable opening in the dam, to allow a regulated amount of water to flow through the dam. Because of the pressure from the backed up water in ...
