Research on the application of digital twin technology for flood and tide prevention in Qiantang River Estuary
To expand the application of digital twin technology in Qiantang River Estuary and enhance the management level of the estuary-related departments,this study starts from the perspective of Qiantang River Estuary water resources management departments,sorts out the business needs for a digital twin of Qiantang River Estuary,and aims at the flood tide problems such as large siltation changes,complex flood tide encountering conditions,and single sea dike warning in Qiantang River Estuary.It constructs digital twin application scenarios for"Four Pre"(prediction,prevention,pre-action,and pre-planning)of flood and tide prevention in Qiantang River Estuary.By iterating and optimizing two key technologies:flood progression forecast and inundation risk assessment for strong siltation estuaries,and real-time assessment of storm tide disasters for strong tide estuaries,this study explores the construction model for flood and tide prevention applications in strong tide estuaries,providing significant support for the construction of a digital twin Qiantang River.The technical application in the 2023 strong tide estuary under extreme siltation conditions for flood risk forecasting and water resource scheduling optimization,the pre-simulation results robustly support the 2023 estuary flood prevention and drainage research,and the safe operation of significant Asian Games venues,providing decision-making base for the related management departments'risk decision-making and flood control scheduling.
