At flood season, reservoir can guarantee the power generation and other benefit only under the premise of ensuring its own safety and the safety of middle and lower reaches of river basin. For maximizing the comprehensive benefits of each reservoir's function, it is necessary to study the scientific operation strategy of single reservoir and reservoir groups. Joint flood control operation of reservoir groups can achieve the task of flood control to maximum extent and balance the water demands of each reservoir's function. Aimed at five controlling reservoirs in the upper Yangtze river, this paper put forward the static and dynamic weight calculation methods of the system safety degree, and developed a joint flood control operation model of reservoir groups with the goal of minimizing downstream flood volume and maximizing system safety degree of reservoir groups. We studied the flood control effect of two operation strategies, the static weight piecewise linear strategy and the dynamic weight piecewise linear strategy, on downstream flood control station under 100-year design flood condition in 1998. The results showed that the dynamic weight piecewise linear strategy can give full play to the role of each controlling reservoir in flood control operation at flood season.
