Abstract:In order to study of the joint operation of Sanbanxi and Baishi cascade reservoirs for small and medium scale floods, this paper analysis the control conditions faced by the cascade reservoirs when operating the small and medium scale floods. Based on current situations, multiple flood operating measures are proposed, the technical and economic comparison research is carried out to determine the recommended measures. Furthermore, this paper propose the joint operation schemes of Sanbanxi and Baishi cascade reservoirs for small and medium scale floods based on the proposed recommended measures, and the joint operation simulation of an actual flood of the target cascade reservoirs show that the proposed schemes are feasible and operable, and so as to reduce the flood disaster risks of the basin and the cascade reservoirs.
