摘要
为提升杭嘉湖平原的防洪决策管理精准化和智慧化水平,实现防洪业务“四预”功能,利用云计算、大数据、人工智能、数字孪生等技术,搭建多源数据整合和高精度动态更新的数据底板,构建知识结构化、智能化分析的知识平台。开发具有杭嘉湖区域特色的基于水文水动力学耦合的洪水预报和圩区洪水风险预警等模型,建立杭嘉湖平原防洪“四预”平台,实现雨水情信息实时感知、洪水动态精准预报模拟、防洪风险区域分析预警、水利工程防洪调度预演和洪水调度预案生成优化。在2021年台风“烟花”等暴雨洪水防御实际应用中,“四预”平台显著提升防洪决策的响应速度、精度和智能化水平。研究成果可为平原河网地区防洪“四预”平台建设提供思路和参考。
To enhance the precision and intelligence of flood control decision-making and management in the Hangjiahu Plain,and to realize the“Four Pre”functions in fl ood control operations,this study applied technologies such as cloud computing,big data,artifi cial intelligence and digital twin.A multi-source data integration framework with high-precision dynamic updates was established,along with a knowledge platform featuring structured knowledge and intelligent analysis capabilities.Regionally tailored models for fl ood forecasting and polder fl ood risk early warning were developed based on hydrological-hydrodynamic coupling.A“Four Pre”fl ood control platform was constructed for the Hangjiahu Plain,enabling real-time perception of rainfall and water level information,accurate simulation of fl ood dynamics,regional fl ood risk analysis and early warning,preview of water engineering flood control scheduling,and generation and optimization of flood dispatch plans.Application of the“Four Pre”platform during Typhoon“Yanhua”in 2021 significantly improved the speed,accuracy,and intelligence of flood control decision-making.The outcomes off er insights and references for the development of“Four Pre”fl ood control platforms in plain river network regions.
