Design and application of digital twin platform based smart Weihe River Basin

With the comprehensively promoting the development of digital twins for large rivers and lakes on a national scale, the construction of a digital twin Weihe River Bain (WRB) has been given high priority. At present, WRB is generally still in the initial stages of smart water construction. The digital twin WRB is being built to address its problems in terms of information, intelligence and digitization. The overall framework of the digital twin Weihe River Basin consists of a digital twin platform and an information infrastructure. The data base is used as the data construction support to supplement and generate the refined L2 data base of the WRB based on the national L1 data base. The professional model as the core of the algorithm provides physical mechanisms and data-driven models. The knowledge base is the driver for intelligent construction to broaden the data dimension of the digital twin WRB. The research has been designed to digitally map and intelligently simulate the entire physical elements of the smart WRB and the entire process of intelligent water management. The results have been applied in the construction of the digital twin based smart WRB. It can provide a reference for further improvement and development of digital twin river basin construction, which also provide ideas for a new phase of smart water development in the Wei River.
