Coastal shoreline movement due to erosion and deposition is a major concern for coastal zone management. Shoreline changes by natural cause or development constructions. Shoreline change is threatening and destroying living things in the marine environment. Topography of coastal area changes frequently due to a drastic sediment movement. In this study, we monitor the shoreline change and movement of sandbar using aerial photographs, satellite imagery and LiDAR data in coastal area, Korea. The result revealed that shoreline near the nuclear power plant showed linear pattern in 1971 and 1980, however the pattern was changed after 2000. As a result of the sandbar monitoring, sandbar moved toward the land. Location and shape of the sandbar have been significantly changed during the monitoring period, from 2003 to 2010. In the future work, we need a precise investigation of the shoreline change and the sandbar movement through the sedimentary and physical studies.
