Research and application of digital twin basin rehearsal scenarios——Taking Nenjiang River main stream as a case
In order to strengthen the reality of the digital twin rehearsal scene and help the precision of decision-making,the digital twin business application platform is built based on the idea of digital twin basin construction.The overall framework and key technologies of twin platform are analyzed,and the panoramic visualization platform of"four pre"for flood control is established,which has the functions of forecast,early warning,rehearsal,and pre-plan.Taking the main stream of Nenjiang River as a case,the practical demands of digital twin construction are analyzed,and the relationship between upstream and downstream inundation losses of Nierji Reservoir is analyzed based on rehearsal scenarios of flood control dispatching of Nierji Reservoir.The optimal dispatching and defense arrangement and suggestions are obtained.The result shows that the panoramic visualization platform can present the real situation of river evolution,ensure flood safety,avoid inundation loss,and provide scientific support for flood control safety decision-making.
