On the Chigasaki-naka coast with 1.4 km length extending between Chigasaki fishing port and Chigasaki artificial headland, beach nourishment using coarse materials has been carried out since 2006. After the start of this beach nourishment, monitoring survey of changes in beach topography has been carried out to investigate beach changes and verify the effect of beach nourishment. In this study, various monitoring data such as the narrow-multi beam survey and photographs of the shoreline taken from a fixed position were analyzed. It was found that beach width of the coast was significantly widened by beach nourishment.
