[Objective]Smart water conservancy is one of the implementation paths to promote the high-quality development of water conservancy in the new stage,and the construction of digital twin basin is the core and key to realizing smart water conservancy.To improve the usability,scalability,reusability and maintainability of the water conservancy model in the construction of the digital twin platform of the Ministry of Water Resources,[Methods]according to the requirements of“standardization,modularization,and cloud service”for the construction of the digital twin basin model platform,using the idea of“divide and conquer+integration”, based on component technology, workflow technology, SOA architecture and container technology, the digital twin ba-sin model platform of the Ministry of Water Resources is constructed. The platform supports the componentized encapsulation and process-building function of hydrological models and intelligent identification models and provides model-sharing and computing services externally through the micro-service form. [Results]The platform design′s rationality and the application′s feasibility have been verified, through the key R&D project demonstration areas-Tunxi Basin and Baihetan Reservoir, “flood forecasting-warning-scheduling” business application and the deformation monitoring business application of project management scope. [Conclusion] The research result can provide some technical support for constructing and applying the digital twin basin model platform.
