摘　　要：水库库区局部水沙运动具有较强的三维性,且水库坝前水沙运动特性及库区冲淤过程十分复杂。为研究水库坝前水沙运动特性及库区冲淤过程,以小浪底坝区为研究对象,采用MIKE3软件建立了小浪底三维水沙数学模型,并利用小浪底水库2013年6月至8月坝前4.5 km内实测冲淤地形及水沙资料对所建模型的适用性与正确性进行了验证。计算结果表明:坝区水位及地形冲淤变化的计算值与实测值基本吻合,因此可认为,采用MIKE3软件模拟小浪底水库坝区的水沙运动及地形冲淤变化是可行的。Flow and sediment movement has the three dimensional characteristics,and the feature of flow and sediment movement in the front of the dam and the sediment scouring-silting processes of the Xiaolangdi Reservoir area are complex. MIKE3 software was adopted to establish three-dimensional water and sediment mathematical model of the Xiaolangdi reservoir in this paper,then we used the measured scouring and silting terrain and water and sediment flow data of 4. 5 km in the front of the dam of the Xiaolangdi Reservoir from June to August 2013 to verify the applicability and validity of the model. The results show that the calculated values of the level in the front of dam and the change of scouring and silting terrain comply with the measured values. So it is certain that three-dimensional numerical model MIKE3 can be used to simulate water flow movement and the terrain change of Xiaolangdi Reservoir area.
