| 摘 要： | 建立黄河下游一维非恒定流水动力学数学模型,并在此基础上建立一维水质模型,采用有限体积法(TVD格式)离散基本方程,通过时间二阶之预测-校正二步格式对离散方程进行求解。该求解方法具有守恒性好、算法简单、通用性强,在预测一般洪水及溃坝洪水波演进方面有较好的实用性,并能对黄河下游突发性污染事件进行初步模拟。

| Abstract: | An one-dimensional hydrodynamic numerical model was developed in the lower reaches of the Yellow River and coupled one-dimensional water quality model,then the finite volume method to used for the basic equation discretization. The discrete equation was solved by using the forecast-revision of second order in time.This method is conservation,simple,easy operation,and better practicability in forecasting general flood and the flood wave evolution of dam-break. At the same,the sudden pollution accident can be initially simulated in the lower reaches of the Yellow River. |
