高含沙河流泥沙数学模型研究

本文推导了高含沙河流的控制微分方程组，在一定条件下，经适当简化，即转化为低含沙河流的控制方程组，可适用于类似黄河这类水沙条件变化较大的河流。确定了高含沙河流模型的参数，给出了适用高低含沙河流的计算程序。选择黄河小浪底坝区为研究对象，对高含沙河流数学模型进行了验证。

The mathematical model study of hyperconcentration river

The controlled differential equations of hyperconcentration river which can transform into the equations for low concentration river by being simplified appropriately is developed, and can apply to the river with very substantial water discharge and sediment load such as the Yellow River. The parameter of the model is decided and a computing program that suits to the river with the different sediment load is given. Finally, the computed channel deformations of river reach near the site of Xiaolangdi Project on the Yellow River are compared with the results of the physical model investigation.
