Analysis of flood limited water level determining methods of reservoir

It is important to reasonably raise the reservoir flood limited water level in order to increase the utilization of the rainwater resources. The methods to set the flood limited water level include the static control and the dynamic control. And the dynamic control methods include the multiple duration method and the dynamic control method. All those methods were summarized and analyzed in this paper, especially the dynamic control. The advantages of the multiple duration method and the dynamic control method for the flood were indicated respectively. Those two methods were contrastively analyzed from the design principles, the application conditions, the actual operation complexity and the risk control factors. Then the conclusion was obtained, that the dynamic control method will be more advantageous and popular than the multiple duration the in the future.
