Abstract: The Taihu Basin is one of the most complex river network, water conservancy projects. The integration of the forecast model and project operations is the key to solving the accurate control of water conservancy projects in the plain river network. Under the background of digital twin basin construction, the framework of the system has been formulated, and the work flow, core function module and critical path has been designed. The "Four pre" system for water conservancy project operations, which integrated the digital hall, digital twin display, "Four pre" operation, consultation assistance, has been established. The system has been developed and deployed. The results show that the whole solution based on digital twin basin framework is feasible. The system has been used in the cooperative projects operation of Yangtze river, Taihu and polder areas. At the present stage, the system realized the replaying of the past flood events, recreating the present and previewing the future. The research results has been applied effectively in the regional flood control and the operation of "water diversion from Yangtze River to Taihu Lake" project, which played an exemplary role in the first batch of digital twin projects of the Ministry of Water Resources.
