Abstract:Dynamic control of flood limit water level for Daqiao reservoir is studied in this paper. Firstly, the accuracy and actual rainfall distribution of short-term rainfall forecast in Daqiao Reservoir are investigated using National Meteorological Center information. The study results indicate that short-term rainfall forecast information can be applied to dynamic control of flood limit water Level for Daqiao reservoir. Secondly, the dynamic control domains for Daqiao reservoir flood limit water level are determined using constrained pre-discharge capacity method. Finally, the dynamic control scheme for Daqiao reservoir flood limit water level is proposed. A case study indicates that the dynamic control scheme will not affect the protecting standards and can effectively improve utilization rate of flood resources.
