The large reservoirs generally undertake flood control, power generation, navigation and many other scheduling tasks. In flood season, flood control is the primary task for reservoirs. Then, how to realize effective utilization of the flood control capacity for flood interception and take into account other comprehensive benefits simultaneously, has become an urgent problem to be solved. In order to solve the problem, a multi-objective optimization model which can give full play to the comprehensive benefits under the premise of guaranteeing the safety of flood control is proposed. With the case study of Xiluodu and Xiangjiaba cascade reservoirs (XXCR), a practical scheme of small and medium-sized floods’ utilization (SMFU) is presented. Finally, the SMFU scheme is applied to the operation in comparison with the original design scheme to verify its effectiveness. The results indicate that the SMFU scheme can improve power generation and navigation guaranteed rate while ensuring flood control safety, which adequately indicates that SMFU is an effective approach to make full use the flood resources in flood season.
