【摘要】 为预测小浪底水库在拟定的调度方案下库区水沙运行规律 ,建立了准二维数学模型 ,并采用黄河三门峡水库及淮河白沙水库的实测资料对模型进行验证。针对设计的水沙系列及拟定的水库调度方式 ,对水库运用初期 1～ 5年的淤积过程进行计算的结果表明 ,水库运用初期大多为异重流排沙 ,库区淤积呈三角洲形态 ,并随运用时间的延长向下游推进更多还原

【Abstract】 A quasi 2D mathematical model is established to predict the water flow and sediment deposition in the Xaiolangdi Reservoir under the condition of proposed operation scheme.The calculation is verified by observation data obtained from Sanmenxia Reservoir,which is located at the immediate upstream of Xiaolangdi Reservoir.The calculated result shows that in the first 5 years the sediment in the reservoir will released by density current and the profile of the deposition is in the form of delta type.The delta will advance forward to the dam gradually.更多还原
