数字孪生钱塘江“四预”应用建设实践

Practice of“Four Preventions”digital twin application for Qiantang River

为解决钱塘江流域治理面临的防洪能力不足、数据整合与利用不充分等问题,提升流域治理的协同性与系统性,利用富春江电站以上预报调度一体化等专业模型,以及工程安全智能感知、潮汐河口动床洪水演进、防洪预报调度一体化等关键技术,通过打造“天空地”一体化流域感知网和多源数据融合数据底板,构建流域防洪预报、预警、预演、预案“四预”功能多跨场景应用,聚焦汛情态势分析及未来趋势预报,实现对流域雨情、水情、工情、灾情的实时监控与精准管理。研究成果在钱塘江流域防洪和杭州亚运会保障方面取得一定成效,可为全国数字孪生流域建设提供借鉴和参考。

To address the challenges of insufficient flood control capacity and inadequate data integration and utilization in the management of Qiantang River Basin,and to enhance coordination and systemization in basin governance,this study integrates specialized models,such as the unified forecasting and scheduling system above Fuchunjiang Dam,and employs key technologies including intelligent sensing for project safety,flood evolution in tidal estuaries,and integrated flood forecasting and scheduling.By building an integrated“sky-earth”sensing network and a multi-source data fusion platform,a multi-scenario application of the“Four Preventions”functions including forecasting,early warning,simulation,and contingency planning is developed.The application focuses on analyzing flood conditions and forecasting future trends,enabling real-time monitoring and precise management of rainfall,hydrological conditions,engineering conditions,and disasters across the basin.The research has yielded positive results in flood control and support for Hangzhou Asian Games within Qiantang River Basin,offering valuable insights for the construction of digital twin basins nationwide.
