Short summary
There is a clear trade-off between reservoir hydropower generation and the variability in reservoir water release, which can be used to derive water-sharing policies and provide critical insights during riparian negotiations regarding downstream flows supplementing during drought conditions. This type of water-sharing policy can effectively mitigate the water use conflicts between upstream and downstream countries, especially during drought periods.
