Abstract

Beach changes of the Kamakura coast including Zaimokuza and Yui-ga-hama Beaches were investigated using past aerial photographs and bathymetric survey data. On this coast, sand back pass using windblown sand at a rate of 600 m³/yr has been carried out as well as beach nourishment. However, the effect of these activities have not yet clarified. Therefore, beach changes were predicted using the BG model proposed by Serizawa et al. to evaluate the effect of the sand back pass and beach nourishment.
