石家庄市城市内涝气象风险监测预警系统研制及应用

Development of Meteorological Risk Monitoring and Early Warning System for Urban Waterlogging in Shijiazhuang

充分考虑石家庄市城市防汛工作的特点和需求,基于城市内涝水动力模型,建立了石家庄市城市内涝气象风险监测预警系统,并对系统的功能结构、系统框架和模型构建原理进行了详细介绍。系统以2017年一次典型强降水过程引发的积涝为例,对系统进行验证对比,结果显示系统在功能实现、模拟精度及运行稳定性等方面都能达到预期设计目标,能够满足业务使用需求。

Considering the characteristics and requirements of flood prevention in Shijiazhuang City,based on the internal hydrodynamic model of city. the risk monitoring and warning system for urban waterlogging in Shijiazhuang City is established in this paper and the functional structure,system framework and model construction principle of the system are introduced in detail. A typical product waterlogging caused by heavy rain process in 2017,for example,is used to verify this system comparison. Results show that the system realize the function,the simulation precision and stability can reach the expected design goal,to meet the demand of business use.
