前浜養浜時の浜崖形成のモデル化

抄録

Analytical and numerical models for predicting beach changes in the foreshore nourishment were developed. In the foreshore nourishment, high beach scarp is formed due to wave action and it is very dangerous for recreational usage of the beach and spoils scenic beauty of the shoreline. The contour line change model was applied for predicting three dimensional beach changes. It is shown that the larger the supplied sand volume to the sea, the higher the scarp height.
