Abstract
On the Ichinomiya coast located near the south end of Kujukuri Beach, beach nourishment using 8,800 m3 of sand was carried out in early July, 2017. To investigate the effect of the beach nourishment, field observations were carried out on May 27, 2017 before the nourishment, July 14, immediately after nourishment, July 22 and August 3, 1 and 3 weeks after the nourishment, respectively, to measure the shoreline configuration and beach profiles. Furthermore, sampling of beach material was carried out along with photographing of the beach. Beach changes after the nourishment was calculated using the BG model proposed by Noshi et al. The measured and predicted shoreline changes were in good agreement. Out of the beach nourishment using 8800 m3 of sand, the volume of beach sand increased by 5400 m3, and 61% of sand remained.
