More than 16 million water conservancy objects in 55 categories, such as reservoirs, river embankments, and flood storage and detention areas, have been updated through information linkage. 2.62 billion pieces of business management data have been dynamically gathered, and 23 domestic remote sensing satellite image resources in a series of high scores, resources, and environments have been obtained through dedicated lines. Digital technology empowers water conservancy construction and development, and all major rivers, national water networks, and water conservancy projects have been included in management. The digitalization, networking, and intelligence level of water management pipes is constantly improving. This year, the digital twin platform of the Ministry of Water Resources has been basically completed, and the construction of the seven major river digital twin basins has been implemented one after another. The digital twin water conservancy framework system has basically formed, and 94 pilot tasks for the construction of digital twin basins have entered the final stage. The construction of digital twin water conservancy has steadily started and achieved phased results. What is digital twin water conservancy, with digital empowerment and smarter water management? Simply put, it refers to the use of new generation information technologies such as cloud computing, big data, artificial intelligence, and virtual reality to collect full data, achieve visual display of river reservoirs, water network construction, engineering scheduling, and conduct intelligent simulation and forward-looking rehearsals. "Cai Yang, director of the Information Center of the Ministry of Water Resources, explained. ——Digital empowerment makes water management more intelligent. At the end of April this year, China's first major digital twin basin construction project - the Yangtze River Basin Full Coverage Water Monitoring System Construction Project began construction. After completion, the monitoring station network will cover 3791 sections and tens of thousands of large-scale water intakes. The video monitoring system can cover 160 controlled water conservancy projects, 96 important flood control nodes, and 28 important sand mining river sections, helping to continuously promote the protection of the Yangtze River. Cai Yang introduced that natural water bodies can be projected into the digital world, and planning, design, scheduling plans, and possible future scenarios can be deduced in advance, providing scientific decision-making for flood prevention and drought relief, water resource management and allocation, etc. ——Smart management makes water use more intensive. The Dujiangyan Irrigation Project Irrigation District, located on the Chengdu Plain, is intertwined with canal systems to ensure water intake. "In the past, due to the low measurement accuracy and different standards, the water efficiency of the irrigation area needs to be improved." Lei Gang, director of the Science and Information Department of Dujiangyan Irrigation Project Water Resources Development Center, introduced that the irrigation area should adjust measures to the canal conditions, install advanced metering facilities, and create 15 standardized water scales. The main canal with a width of over a hundred meters has high water level and large waves, and side mine sweeping and measuring water scales are installed; Branches and channels several meters wide, with small water volume, are equipped with contact type water level measuring scales. Real time measurement of water volume, water level, and other data. As much water is used, the amount of water is put in, and a water scale is used to measure it. Large and medium-sized irrigation areas are important infrastructure for ensuring food security. Modern information technologies such as the Internet of Things, artificial intelligence, and 5G cover the fields and fields, making supply, transmission, distribution, irrigation, and drainage more intelligent, and agricultural water use more secure. The Ministry of Water Resources has fully launched the construction of 48 digital twin irrigation areas. The construction of digital twin watersheds, digital twin water networks, and digital twin projects is constantly advancing. The first batch of provincial-level water network pilot areas such as Guangdong and Zhejiang, the second batch of provincial-level water network pilot areas such as Anhui and Ningxia, and the start of digital twin water network construction for the South to North Water Diversion Project; The construction of 11 key digital twin water conservancy projects such as the Three Gorges and Xiaolangdi has achieved significant results. At present, the number of online monitoring and measurement points for water intake in China has increased to 59000, with over 38000 points
