Abstract: In recent years, with the rapid economic and social development, the contradiction between reservoir flood control and comprehensive utilization of water resources has become prominent. How to make full use of water resources under the premise of improving the safety and security of flood control in the basin is a problem worthy of discussion. Based on many years of reservoir operation practice, this paper analyzed and discussed the comprehensive utilization of water resources in flood control operation of reservoirs in flood season from the aspects of the implementation of limited water level in flood season, the control of operation water level in flood season, the operation of frequent floods and the risk avoidance of large floods. It was suggested that the dynamic control of reservoir operation water level in flood season and the advance water storage at the end of the flood season should be paid more attention. Based on the research and application results of small probability flood control risk, the basic work of rainfall flood forecasting, flood area composition and flood characteristics analysis should be further promoted, and the multi-level flood control operation system oriented to "time-space-quantity" should be constructed.
