Recently, Jeongdongjin Beach in Gangneung, Gangwon–do, in the eastern part of South Korea, has been seriously eroded, and several parts of the revetments along the coast were subsided due to frequent high wave attacks. Thus, several parts of the Jeongdongjin rail bike track and facility in the southern part of Jeongdongjin station were damaged and washed out. In this study, field surveys and measurements (including waves, current, water depth, seabed material, beach profile, and shoreline) at Jeongdongjin Beach 2014–2015 were conducted to analyze and determine the erosion process. From the surveys and...
