基于水文仿真模型与GIS的三维可视化在城市洪水演进中的模拟研究——以马鞍山为例

本文对城市三维可视化虚拟场景构建和洪水演进实时动态模拟及其实现方法进行研究。以洪水水文数学模型为核心计算方法,对系统构建过程中的关键技术进行了深入探讨和研究,构建了城市洪水演进和洪水淹没三维模拟系统。研究表明,三维可视化技术与水力学模型结合提高了模型计算结果的准确性和可视性,对于城市防洪决策及水利工程有重要意义。以安徽省马鞍山市为应用实例,实现了城市三维地形仿真场景模拟及洪水演进分析和三维模拟。

Three-dimensional visualization simulation of flood routing of city based on hydrological mathematical model

Based on the study on both construction of 3D-visualization of city scene and real time dynamic simulation of flood routing,this paper advanced an implementation method of 3D simulation system to simulate flood routing and submergence.Using of hydrological mathematical model is the core of the research on visualization of city flood protection.This method was presented in the extent of Ma'anshan city in Anhui province,which is along Yangtze River.3D terrain scene of Ma'anshan city was constructed.Under this...
