Trade-Offs Model Of Multi-Objective Reservoir Operation With Uncertainties

As the increase of water resources management and exploitation goals, it is gaining increasing weights for reservoir operation to seek optimal options for the balance between multiple and contradictory water resources use objectives. This study develops a trade-offs model to quantify the economic benefits of reservoir operation rules on the downstream water supply yield. Uncertainties of different water use benefits are considered by using a Monte Carlo method in the trade-offs model. The case study is analyzed to evaluate its performance in terms of water use benefits of agriculture, hydropower, flood control and environmental water requirements in the Yellow River, China. Trade-offs results are got among water resources needs of social development and environmental protections under the reservoir operation. The results indicate that there are magnificent trade-offs between ecological benefit and social economic development under different management policies and scenarios. This study could provide a simple but robust framework for quantifying the consequences of management options with reservoir operations under control. The results could be used for reference of compromised solutions to the ecological and human negotiations for water.
