Research on construction of"Four Preventions"digital twin application for flood control in Feiyun River Basin
The Feiyun River,one of Zhejiang's major rivers flowing directly into the sea,is prone to large-scale basin floods.To address key challenges in flood and tidal disaster defense in the basin,including insufficient information sharing,inadequate flood forecasting and scheduling capabilities,and weak integrated engineering scheduling,this study explores the construction of a digital twin application for the"Four Preventions"in flood control.By developing a multi-source data fusion platform with unified governance,the study establishes a comprehensive flood coupling model spanning"rainfall-runoffgeneration-flow concentration-evolution-risk assessment".A knowledge platform centered on historical storm and flood events was created to support the implementation of the"Four Preventions"in the Feiyun River Basin.During the response to Typhoon Doksuri in 2023,rolling flood forecasts were conducted,warnings were issued promptly,multiple scheduling scenarios were simulated,and contingency plans were rapidly devised,streamlining all aspects of flood control and disaster reduction.This marked a shift from"experience-based defense"to"intelligent defense",providing a pioneering demonstration for constructing digital twin flood control applications in coastal river basins flowing directly into the sea.
