The primary purpose of the three upstream reservoirs is hydropower generation; however, the fourth one plays a vital role in water supply and irrigation. The management of the water resources related this river to date has been restricted mostly to hydropower. Nevertheless, the increasing water demands for households, industry and agriculture may potentially be met by improved water management policies. This study therefore recommends a better strategy for hydropower generation to increase the amount of energy that will be generated and to mitigate the water supply shortage. The GWASIM model (Chou and Wu 2010) is applied in this paper, which is based on Network Flow Programming, to simulate the daily hydropower generation and water resource allocation for the system. The model set up includes the main river and tributaries with 33 years of inflow data and demand requirements for the year 2015. Regulation strategies for hydropower generation of cascade reservoirs were evaluated and compared. Strategies and scenarios of different water allocation priorities and rations were also simulated and compared. The results showed that when domestic and industrial demand has the first priority access to water, and energy generation comes second, the shortage index of all demands was reduced and the hydropower generation was essentially the same in both strategies. This improved strategy for operating cascade reservoirs can improve energy production from hydropower as well as water supply for domestic demand and irrigated food production.
