Study on Erosion Along the Suizhong Coast of the Liaodong Bay

In this paper,the erosional characteristics along the Suizhong sandy coast of the Liaodong Bay are analyzed by comparing nautical charts in different periods and analyzing remote sensing images and multi-year field monitoring data,and it is shown from the analysis results that the loose coastal sediments and intense coastal dynamic actions are the basic conditions for the recent coastal erosion,and the decrease in terrigenous material discharged into the sea,marine dynamic actions,coastal engineering structures and offshore sand recovery are the main affecting factors for the coastal retrogradation.
