Abstract
In order to investigate the mechanism of topographic changes of the foreshore due to wave action, field data obtained at Ajigaura Beach once a week since 1975 were analyzed. Dominant factors determining foreshore changes are found to be energy flux of the deep water waves, grain size on the foreshore and foreshore slope. Accretion or erosion of the foreshore can be classified using these three parameters. Beach lamination process of the foreshore was investigated through the field observations at Ajigaura Beach. It is found that berm can be formed by some sublayers composed of coarse and fine materials or only by one layer composed of fine material. These changes can be elucidated by the wave climate change.
