【 摘 要 】

When beach changes occur owing to the imbalance of longshore sand transport, not only bathymetric changes but also grain size changes occur, having an impact on the coastal environment. With the increase in the anthropogenic impact, such changes have been observed on many coasts. Here, the bathymetric changes and changes in grain size of seabed materials were investigated on the basis of a numerical simulation using the BG model (a three-dimensional model for predicting beach changes based on Bagnold’s concept), with northern Kujukuri Beach in Japan as the study area.
