Construction and application of four pre-platform for flood control of digital twin Qinhuai River Basin
For the realization of the Qinhuai River Basin water disaster prevention accurate forecast warning and intelligent dis-patching decision,based on the current situation of flood control and the requirements of the Ministry of Water Resources'digital twin basin construction,using a series of key technologies to integrate the four pre-cautions(forecasting,early-warning,exer-cise,and emergency plan)of flood control into the business process,a four pre-platform for flood control and disaster reduction in the basin was established.The key technologies included three-dimensional monitoring of space-air-ground,data rule min-ing and knowledge discovery,water conservancy dynamic knowledge map,hydrological-hydrodynamic multi-factor process mu-tual feedback mechanism and model coupling,model parameter optimization and dynamic correction,multi-objective dynamic de-cision-making and scheme intelligent generation,flood risk analysis and assessment,etc.The availability of the platform was veri-fied by using the historical flood scene and flood control exercise process of the basin.The results showed that the platform can re-alize real-time monitoring of the Qinhuai River Basin,find problems,and optimize scheduling,so as to achieve the purpose of early detection of risks,early warning,early formulation of plans,and early implementation of measures.The research results can provide construction ideas and case references for flood control construction in other digital twin basins.
