                   Abstract:The flushing operation of Sanmenxia Reservoir during the flood season is a key approach to han⁃
                   dling the problem of sedimentation and restricting of Tongguan Elevation. Since the application of“Storing
                   Clean Water and Discharging Muddy Flow”(SCWDMF), dynamic balance of scour and deposition in the
                   reservoir has been generally maintained by lowering water level in flood season to flush the cumulative sedi⁃
                   mentation during non-flood season. Different water levels operations and reservoir flow processes have differ⁃
                   ent sediment flushing effects. In view of the differences in the sand discharge process of Sanmenxia Reser⁃
                   voir, statistical characteristics of sediment discharge in flood season since SCWDMF were adopted to ana⁃
                   lyze the influence of reservoir open discharge and water level operations on sediment discharge. The results
                   show that under the operation of normal water lever of 305m and open discharging in flood period, sedi⁃
                   ment discharge has the characteristics of more coming and more discharging,and the total amount of sedi⁃
                   ment discharge in flood season is closely related to the incoming runoff and sediment concentration; When
                   the reservoir is fully ungated discharging, reservoir scour depends on the flow rate and the open duration,
                   with the net efficiency of sediment discharge decreasing with the flow increase and open duration exten⁃
                   sion; When the water level is controlled between 305-311m, sediment discharge occurred as the flow is
                             3
                   above 1000m /s with the efficiency depending on the retention time of the sediment-laden flow in the back⁃
                   water section and the ratio of the inflow and outflow discharge. This research provides basis for the optimi⁃
                   zation of Sanmenxia Reservoir operation.
