River basin flood control simulation has problems such as low rendering efficiency, poor simulation effect, lack of real geographic coordinates, high requirements for client configuration, and unsystematic simulation functions. Taking the key flood control objects in the Yangtze River Basin as pilot projects and based on the digital twin basin framework, a simulation system for four prediction flood control results was designed. Combining the advantages of GIS engine and game engine, high fidelity rendering technology and four prediction flood control simulation technology for the basin were studied. And then a digital twin scene development tool was constructed to achieve the key flood control simulation of the Yangtze River Basin. The practical application shows that the flood control business simulation technology system solves the common problems in the flood control simulation process of the watershed, and provides reference for other watersheds to build digital twin watershed systems.
