渭河下游河道及洪泛区洪水演进的数值仿真(Ⅱ)——成果分析及可视化
Numerical simulation of flood in downstream of Weihe River and flooded area (Ⅱ)——Results analysis and its visualization
【摘要】 采用数值模拟方法模拟渭河非恒定流动,给出河道一维和洪泛区二维的数值模拟结果,分析比较了洪水的传播特性、河道溃决与不溃决对洪水传播的影响.同时,基于VB语言实现了河道和洪泛区洪水演进的动态演示,为防洪调度和决策提供了可视化的工作平台.
【Abstract】 The numerical simulation method for unsteady flow is used to calculate the flow in the Weihe River; the results of 1D model for main channel and 2D model for flood area are presented. The flood promulgate behavior is analyzed. The effect of bank-break on flood is discussed. The visualization system for the Weihe River flood is formed by Visual Basic language. It can provide working platform for preventing or controlling flood and its decision-making.
