| 摘 要： | 基于圣维南方程组建立河渠一维洪水演进模型,用Matlab编制程序进行计算并将结果数据导入到Arc-GIS中,实现各断面水位和流量的实时动态显示,同时利用Matlab的作图功能绘制每个断面的水位、流量随时间变化的过程图,从而实现了城市公共安全应急系统中一维洪水演进的实时可视化.

| Abstract: | Based on Saint Venant equations,the river one-dimensional flood evolution model is establinhed.The Matlab is used to compile program for calculation and lead the outcome data into ArcGIS to achieve real-time dynamic display of the water level and flux in each vertical section.Then the graphic function of Matlab is used to produce the course of drawing for the water level and flux in each vertical section with time movement,to achieve the real time visualization of one-dimensional flood evolution model in urban public safety emergency system. |
