“2D城市洪涝与流域汛情风险预警评估系统”应用探讨

Investigation and Application of Risk Pre-warning Assessment System for 2-D Urban Flood and Drainage Area Flood

城市洪涝预警预报对保障城市正常运转意义重大。为有效地提升洪涝预警评估水平,有必要借鉴国外的先进方法与技术。"2D城市洪涝与流域汛情风险预警评估系统(FRMFS)"在技术上属国际先进水平,浙江省引进后,结合实际进行消化、吸收、二次开发,从数据采集、预报模型等方面验证了其在中小城市中的适用性。实例成果表明该系统对有效提升城市防汛抗灾综合能力具有实际意义。

Prediction and pre-warning of urban flood is of great importance to secure the normal operation of a city. In order to efficiently improve the ability of risk pre-warning assessment for urban flood, it is necessary to utilize the advanced method and technique from overseas. The risk pre-warning assessment ability system for 2-D urban flood and flood situation of drainage area （FRMFS） which was introduced into Zhejiang province was at advanced inter-national level. In line with the actual situation of China, this technique was absorbed, assimilated and redevel-oped. It＇ s applicability for towns, mid-sized and small cities are verified from the aspects of data acquisition, pre-diction model, and results display. The achievement of some real cases indicates that this system can efficiently im-prove the ability of risk pre-warning assessment for urban flood.
