Since the beginning of 2025, China's water conservancy industry has undergone significant changes, with the accelerated construction of a digital twin water conservancy system shining brightly, achieving remarkable positive results in the field of water conservancy governance and management, and promoting the country's water conservancy industry to make great strides towards intelligence.

At the level of monitoring and perception, an integrated monitoring and perception system for "sky ground water engineering" has been basically established, achieving comprehensive, multi-level, and three-dimensional collection of water conservancy information. This system has a grand scale, covering 31 remote sensing satellites, over 100 water conservancy rain monitoring radars, more than 4000 drones, 133000 ground hydrological monitoring and reporting station facilities, and 310000 water conservancy engineering safety monitoring points. With the help of "Water Conservancy No.1" and multiple remote sensing satellites in the network, all-weather monitoring of flood, drought, and ice conditions can be carried out to ensure timely grasp of water situation dynamics at any time; Drones are equipped with advanced equipment such as infrared cameras and laser radars, which can initially achieve external detection of dam leakage, piping and other issues, providing protection for the safety of water conservancy projects.

In terms of flood control capacity building, the country actively promotes the construction of flood control forecasting, early warning, rehearsal, and contingency plan capabilities in seven major river basins, and has achieved remarkable results. Researchers have developed a series of advanced models, including the "cloud rain" precipitation forecasting model, fractional flood forecasting model, hydrodynamic flood propagation director model, etc. The application of these models further extends the flood prediction period, improves forecast accuracy, and provides solid and powerful support for resisting basin floods. Through accurate forecasting and early warning, relevant departments can take preventive measures in advance, organize personnel evacuation and material allocation; The rehearsal function can simulate and deduce different flood control plans, and select the optimal plan; The formulation and improvement of contingency plans ensure that response work can be carried out quickly and orderly in the event of floods.
