数字孪生曹娥江流域试点建设实践与探索OA

Under the context of the Ministry of Water Resources digital twin basin development and Zhejiang Province's digital reform,practice and exploration of the digital twin pilot development in the Cao'e River Basin have been undertaken to address the region's needs for integrated forecasting and dispatching,closed-loop risk and hazard control,and collaborative flood control and disaster reduction.Following the overall architecture of the digital twin development in the Cao'e River Basin,key technologies are focused,such as the construction of L2 and L3 level database,the integration of the entire process coupling model,and the intelligent decision-making model for optimizing reservoir group dispatching.The intelligent flood control application of the Cao'e River Basin has been developed,achieving the establishment of"four pres"scenarios for forecasting,early warning,rehearsal and pre-planning,as well as online analysis of"three maps and one list",and the flexible application of three scheduling modes.The research results can promote the reshaping of the core business process of flood control in the river basin,achieving integration throughout the entire flood control chain.These outcomes have been applied in the practical defensive against typhoon Xuanlannuo and typhoon Meihua in 2022 with positive results,thereby providing technical demonstration and experience reference for the development of flood control applications in digital twin basin.
