摘要
Abstract
The disaster of bank collapse poses a serious threat to the economic construction and the safety of people's life and property along the river.Aiming at the problems of low efficiency and heavy workload of the current analysis method of underwater bank slope in Yangtze River and Han River sections,we proposed an automatic analysis method.We calculated the bank slope ratio and steep slope automatically in the longi-tudinal section of river,and used an automatic merging algorithm to extract the steep bank at first.Then,we analyzed the whole and local changes of steep bank lengths in different years.The result shows that the proposed method can quickly complete the processing of a section,greatly improve the extraction efficiency of underwater bank slope,and provide intuitive and comprehensive analysis results to serve the empirical assessment method of bank collapse.关键词
