Abstract:
The Smart Yangtze River supported by the Digital Twin Yangtze River is an important new infrastructure to accelerate the realization of the goals of the Safe River, the Green River, the Harmonious River, and the Beautiful River in the new stage of high-quality water conservancy development. Focusing on the short-term objectives of the construction of the Smart Yangtze River, this paper expounds the construction requirements, development background, construction goals and the overall structure of the Smart Yangtze River supported by the Digital Twin Yangtze River. Guided by the problems, this article focuses on the standardization of models, the integration of data-driven methods and mechanistic models, and the application of model configuration tools. The methods of construction a knowledge graph for flood control is proposed. On this basis, a business application for intelligent operation of water projects with forward simulation and backward deduction is presented. Finally, the implementation path for integrating new and old systems is explored, which provides technical support to further promoting the construction of the Smart Yangtze River.
