Abstract


The temporal and spatial beach changes on the Fuji Coast are elucidated through this study, and the 1i t toral transport rate on the downdrift coast of Tagonoura Port is evaluated. In particular, it is concluded that a large amount of sediment eroded from the downdrift beach of Tagonoura Port is carried away toward a zone deeper than 20m. The second aim of this study is to devel op a numerical model whi ch can predict three-dimensional beach changes. For this purpose, a model in which the vertical distribution of littoral transport is taken in to account and the effect of the wave-dissipating breakwaters on the beach changes can be evaluated is developed.
