三门峡水利枢纽从1989年起汛期进行浑水发电试验，优化汛期调度运用。最近几年汛期，在深入分析进出库水沙变化和冲淤情况的基础上，合理地进行了水沙调节。汛期发电与排沙分阶段运用，洪水多沙期降低水位泄洪排沙，恢复库容；平水期控制305m水位发电，入库泥沙经坝前空水段分选，出库泥沙减少，颗粒细化，过机水流减沙效果更为显著。选择适当时机排沙3～4天，全水淤积物可全部清出库外，库容恢复后调沙效果进一步提高。回水末端以上河道不受空水影响，河床冲刷继续发展。
Sanmenxia Hydro Project from 1989 flood season muddy water power generation test to optimize the use of flood season scheduling. In flood season in recent years, on the basis of in-depth analysis of the change of sediment and sediment flow in and out of reservoirs and reservoirs, the regulation of water and sediment is reasonably carried out. In flood season, power generation and sedimentation are applied in phases. During the flood period, the flood discharge and sediment discharge is reduced, and the reservoir capacity is restored. The 305m water level is controlled during the flat water phase to generate electricity. The effect of sediment reduction over the water flow is more significant. Select the appropriate time for sand 3 ~ 4 days, all the water silt can be cleared out of storage, storage recovery after the sand effect to further improve. The river above the backwater is not affected by the empty water, and the riverbed erosion continues to develop.
