摘要
为浙江省编制洪水风险图始于1989年,根据浙江省的洪水灾害特点,基本资料情况等,采取了以历史水灾-水文学法为主的洪水风险分析方法,而在水库溃坝风险分析中运用了水力学二维仿真模型。在洪水风险图的基础上还延伸开发了水灾损失评估系统,并在防御台风、洪水中发挥了显著的减灾效益,同时也为其他领域提供强有力的科学决策依据。
Flood hazard mapping in Zhejiang province started in 1989. Method used for flood risk analysis is mainly historical flood-hydrology, according to the character of flood and basic data in Zhejiang province. Two-dimensional emulation model of hydraulics was used in dam breach risk analysis. Flood loss assessment system was developed on the basis of flood hazard mapping, which played a key role in protecting typhoon and flood and also provided a scientific base for making decision.
