摘要
为实时、快速、全面地获取山洪发展趋势及其时空变化信息,利用三维GIS技术和网络计算技术,无缝集成气象数据、地理信息数据、气象三维模型等,以三维仿真模拟探讨了由强降水引发的河北省山洪灾害汇流模拟及淹没分析技术,建立了河北省山洪灾害汇流模拟分析系统。该系统可为山洪灾害风险的科学预警提供技术依据和决策支持。
In order to obtain comprehensive information on trend of mountain flood and its temporal and spatial variation in real time and fast speed manner, new technologies are applied, including 3D GIS and network computing,seamless integration of meteorological data and geographic information as well as weather 3D model. Three-dimensional simulation has been used for analyzing runoff generation of mountain flood and inundation caused by strong rainfall, so as to establish simulation system in Hebei Province. It is expected to provide a technical base and decision-making support system for elimination of mountain flood disasters.
