Digital twin water network construction method and computer equipment

The invention discloses a digital twin water network construction method and computer equipment. The method comprises the following steps: based on a water conservancy map and the like, obtaining a river and lake object, drawing up a solution, compiling node observation station information, checking line and plane data of an observation point, counting adjacent nodes, generating a river and lake node topological relation table, automatically checking and forming a river and lake node topological model. The digital twin water network information comprises scheme codes, node ID numbers, observation station codes, node names, node classes, observation station classes, rain harvesting areas, river reach lengths, river bottom elevations, adjacent node numbers, adjacent node ID numbers and the like. And the node ID number and the adjacent node ID number are associated with each other to form a river-lake node topology model to reconstruct a physical drainage basin, and a digital twin water network facing a water mo
