1994年汛期三门峡水库运用情况及冲淤特点

Operation Conditions and the Characteristics of Erosion and Sedimentation of the Sanmenxia Reservoir during the Flood Season of 1994

通过对三门峡水库１９９４年汛期各阶段的水沙条件、运用情况、冲淤变化和水沙调节等特点进行分析，提出了汛期排沙与发电应分阶段运用，并根据水沙变化和库区冲淤情况适时调度、合理调水调沙的运用方式，有利于库区泥沙冲淤平衡、降低潼关高程、减少过机泥沙、提高发电效益。浑水发电，泄洪排沙，冲淤平衡，三门峡水库，汛期。

nalyses of the characteristics of runoff and sediment load regime, operational conditions,change of erosion and sedimentation and water and sediment regulation at each stage of the 1994flood season are described. Sediment releases and electric power generation by stages during floodseason, operational mode of timely dispatching and rational water and sediment regulation according to changes in the runoff and sediment, and erosion and deposition in the reservoir area are alsoraised out in order to make erosion and sedimentation balance in the reservoir area, to lowerTongguan elevation, to reduce the sediment through turbines and to increase benefit of powergeneration.
