Abstract
This paper deals with long-term sea-level change along the coast of Sea of Japan (East Sea) and an expectation of shoreline retreat by sea-level rise. Tidal level data have been analyzed by 12 months moving average and this result shows a tendency to rise. Wave tank experiment shows not only static retreat by water-level rise but also additional retreat by waves plays an important role in total retreat by water-level rise. Shoreline retreat has been predicted with some assumptions using analyzed sea-level data.
