Bank-Collapse Monitoring Technology for the Middle and Lower Reaches of the Yangtze River

Significant alterations in water-sediment conditions have placed the riverbed of the middle and lower Yangtze River in a state of intense scour, resulting in frequent bank-collapse hazards. Bank collapse is one of the important manifestations of river erosion. To counter the threats that bank-collapse poses to flood control, navigation and shoreline utilisation, the Bureau of Hydrology of the Changjiang Water Resources Commission has developed an integrated monitoring system that blends traditional methods with advanced technologies and combines qualitative observations with quantitative measurements under an information-platform framework. Early reliance on manual patrols and topographic surveys has gradually expanded to multi-source monitoring that merges LiDAR, multibeam bathymetry, satellite remote sensing and UAV patrols, and finally to the establishment and application of an information-based early-warning platform. Looking forward, bank-erosion monitoring will be deeply integrated with the latest digital-twin, big-data and AI technologies to build dynamic data bases, achieve real-time hazard identification and rapid response, and enable long-term morphodynamic simulations and scenario forecasting—thus providing robust technical support for the secure and sustainable development of the Yangtze River corridor.
