Abstract: The dynamic control of operating water level of the reservoir in flood season is of great significance for basin flood control.For the annual regulation reservoir,it is often faced with the contradiction that the reservoir discards water in flood season and lacks water after flood season.To address this issue,taking a large reservoir of Jiangya in Lishui Basin of Hunan Province as an example,we analyzed the feasibility of adopting dynamic operation and control for the operating water level of reservoir in flood season from the aspects of the flood forecast,weather and rainfall as well as the pre-discharge capacity of the reservoir,and then determined the dynamic operation and control scheme,and analyzed the benefits of flood control,drought resistance,water supply and power generation under the dynamic control.The result showed that under the dynamic water level control of the reservoir in different periods,not only the flood control effect of the reservoir was not affected,but also comprehensive benefits such as the power generation,the drought resistance and the ecological water supply of the reservoir were brought into full play.The research results can provide a reference for the scientific operation of other reservoirs.
