Abstract
To ensure the safety of the embankments and important infrastructure along the main stream of the Yangtze River,monitoring and early warning measures are implemented for the bank collapse of the Yangtze River estuary in Changshu section.Through scientifically defining the monitoring scope,this paper elaborates in detail on the measurement operation process,system calibration,water depth and land area measurement,data processing methods,especially the implementation of water depth measurement by combining single beam and multi beam technologies.By comparing the 2024-1 measurement with previous measurements through month on month and historical erosion-siltation calculations,it is concluded that the lower section of the Tiehuangsha Regulation Project shows a silting trend,while the Xuliujing Node Section shows an erosion trend.Subsequent monitoring suggestions are proposed for potential issues affecting river regime and dike safety,providing technical references for similar dangerous work monitoring.关键词
