Abstract

of as the change analysis using past photographs. When the volume change of the beach was the in the foreshore area between and 2018, and was by the characteristic height of beach changes of 3.1 m, eastward longshore sand transport on the north coast of the cuspate foreland was evaluated to be 1,160 m 3 /yr, assuming that sand supply from the south side was entirely disrupted. Sandy beach has been disappearing owing to the imbalance in longshore sand at Futtsu cuspate foreland.
