改进河道洪水演进模型在漳卫河的应用

在一维非恒定流水动力模型的基础上耦合堰闸水动力模型，采用三级解法构建了一维水动力河网模型，并把改进的模型应用到漳卫河中，进行历史洪水重现模拟。结果显示，模型适用性强，能够很好的处理河流交叉、堰闸过流等问题，可以为漳卫河的防洪调度提供技术支持。 The one-dimensional unsteady flow model and weir gate hydrodynamic model were coupled to develop the one-dimensional river hydrodynamics model using the three-gradation method. The model was applied to simulate the historical flood in the Zhangwei River. The results showed that the model is applicable to solve the problems of the river crossing and overflow of weir gate, which can provide technical support for the flood operation in the Zhangwei River. 水利部公益性行业科研专项经费项目（201101026；201101024；201301001；20131102）；环保部公益基金项目（2013467042）；国家973课题（2013CB036406）
