摘要
根据渭河下游河道水沙及河床演变特性，提出了黄河倒灌渭河的数学模型。该模型不仅适用于黄河倒灌渭河时渭河下游河道水位、流量、含沙量及河床淤积的数值模拟，也适用于其它双向水流及干支流交汇或分流河段的水沙计算。验证计算表明，该模型能较好地反映黄河倒灌渭河时渭河下游水文泥沙因素变化。
A one-dimensional unsteady and non-equilibrium transport mathematical model is presented. It may not only be used to simulate the water level, discharge, sediment concentration and sediment deposition when the Yellow River intruding into the Weihe River, but also be used to calculate the water and sediment of a reach which has two-direction velocity or tributary inflow. The verified results show that the model can simulate the whole process of the changes of hydrologic and sedimentary elements in the downstream of the Weihe River.
