Construction practice and effectiveness of digital twinning of Beijiang River Basin
In response to the frequent occurrence of flood disasters in Beijiang River Basin,and aiming to improve the flood control and disaster reduction capacity of Beijiang River Basin,Guangdong Department of Water Resources organized the construction of digital twin of Beijiang River Basin.The digital twin of Beijiang River Basin is based on the public capacities of Guangdong Province's big data platform,model platform,and knowledge platform,focusing on joint optimization dispatching for flood prevention.It deeply integrates the flood prevention engineering system comprising reservoirs,flood detention areas,sluice gates,and flood diversion channels,levees in Beijiang River Basin with digital twin technology,coordinating the optimization of multiple engineering group linkage for"upward adjustment,middle control,and downward diversion".A complete"Four Pre"framework of forecasting and early warning-engineering scheduling-river progression-precise simulation-risk assessment-pre-plan execution has been established.The digital twin Beijiang effectively supported the defense against the"22·6"extraordinary flood and the first flood of 2024 in Beijiang River.The related achievements have been promoted and reused in the digital twin water network,digital twin Dongjiang,etc.
