Concept, Key Technologies and Challenges of Digital Twin Riverbasin

According to the new needs of riverbasin management, the deep integration of new generation information and communication technology riverbasin monitoring and management, and the establishment of a digital twin riverbasin to achieve accurate simulation of riverbasin simulation and intelligent management decision-making have become hot spots in the industry. Starting from the basic concept, motivations and innovative management of the digital twin, this paper puts forward to the basic definition and characteristics of the digital twin riverbasin, the technical framework of digital twin riverbasin, and the key technologies and the facing challenges of the digital twin riverbasin, and proposes a digital twin riverbasin triangle design model based on the characteristics of the riverbasin scenario.
