Water conservancy monitoring system and method based on digital twinning

The invention belongs to the technical field of water conservancy monitoring, and relates to a water conservancy monitoring system and method based on digital twinning, and the method comprises the steps: constructing a watershed digital model based on SWAT through a watershed digital model generation module; integrating data of each sensor deployed in the target drainage basin into the drainage basin digital model through a drainage basin data integration module; a hydrological dynamic simulation module simulates the hydrological dynamic state of the target drainage basin in the drainage basin digital model based on the digital twinborn technology, and predicts an area with a water and soil loss risk in the target drainage basin; a risk warning module reports the position information of the sub-region with the water and soil loss risk in the target drainage basin, and feeds back warning information to a corresponding management personnel terminal; by marking the position information of the sub-region with th
