平原河道支流水量交换数值模拟方法

Numerical simulation of tributary water exchange in plain rivers

简要介绍了4种平原河道支流水量交换的模拟方法,即干支比法、调蓄滩地法、调蓄单元法和反分析求解法.并应用这4种模拟方法分别计算了苏州河与黄浦江的水量交换.其结果表明,调蓄单元法和反分析求解法具有较高的模拟精度.

Four numerical simulation methods for tributary water exchange in plain rivers, which are the method of ratio between arterial and tributary, the method of storage of bottomland,the method of storage of cell and the method of reverse analysis are briefly introduced, and the four methods are used to calculate the water exchange between Shuzhou River and Huangpujiang River. Calculation results show that the method of storage of bottomland and the method of reverse analysis have high simulation accuracy.
