武汉市城市积涝预警系统及其仿真模拟效果

Study on the Early Warning System for Rainstorm Waterlogging in Wuhan City and its Simulated Results

摘要: 在建立武汉市城市排水管网地理信息系统的基础上,以城市地表与明渠、河道的水流运动为主要模拟对象,以二维非恒定流基本方程和无结构不规则网格划分技术为骨架,设计了适合武汉市的城市积涝仿真模型,并结合精细化降水预报业务和积水

Abstract: Based on the geography information system for drainage network, a simulation model for waterlogging in Wuhan City was established on the basis of two-dimensional unsteady flow theory and the technique of nonstruc
