二维洪水演进数值模拟研究

Discussion on Numerical Modeling of 2-D Flood Routing

洪泛区洪水演进数值模拟是风险分析与居民防洪避险等非工程措施的重要依据。从洪泛区模拟的必要性、二维洪水演进的数学模型、对数学模型求解的数值计算方法、离散计算域采用的网格、洪水模拟程序设计、模型的率定和验证等方面对洪水演进数值模拟进行了论述。

Numerical modeling of flood routing in flood area is important basis of non-engineering measure, such as analysis of flood risk, people's escaping from risk of flood and so on. This report analyzes essential of flood simulation?mathematics model of 2-D flood,calculation method of mathematics model, meshes of separating calculation area,program design of flood modeling, calibration and verification of the model.
