At Imagire-guchi tidal inlet connecting Lake Hamana to the Pacific Ocean, a jetty had been extended by 1973 to stabilize the entrance channel of the inlet. Although 45 years has passed from the completion of the extension of the jetty to 2018, large topographic changes are still occurring offshore of the tidal inlet. One of the authors investigated the topographic changes until 2005, and the beach changes around the inlet were analyzed using the BG model (a model for predicting 3-D beach changes based on Bagnold's concept). In this study, topographic changes were analyzed again using the bathymetric survey data collected by 2017, and the development and deformation of the ebb tidal delta were studied.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/V1o3QXO-q1g
