小浪底水库运用初期下游河道冲淤数学模型预测计算

Mathematical Model of River Bed Change Downstream of Xiaolangdi Reservoir in Early Operation Period

本文采用清华大学与黄河水利科学研究院共同研制的黄河小浪底水库下游河道冲淤数学模型和三门峡水库蓄水运用及滞洪运用初期实测资料 ,开展了系统的验证计算 ,并以此为基础 ,对小浪底水库运用初期下游河道的冲淤变形趋势进行了预测计算 ,其计算结果对小浪底水库初期运用方式的制订具有指导意义。

Based on the mathematics model of river bed change downstream of Xiaolangdi reservoir developed by Tsinghua University and Institute of Yellow River Research,numerical prediction of erosion and deposition downstream of Xiaolangdi Reservoir in early operation period are carried out in this paper,and a series of scientific suggestions are given for reservoir operation managemont in early operation period.
