短期および長期における３次元海浜変形予測に関する一考察

Abstract

This study is concerned with the prediction method of 3D beach evolution in the long-and short term. As the first step, a 3D morphodynamic model, Q3D-CAM (Coastal Area Model based on Quasi-3D nearshore current model), is proposed. First, in order to investigate the characteristics of the presented model, model tests associated with a detached breakwater were carried out. Secondly, the applicability of the model to the prediction of sand bar movement in the short term was examined, and also the model was applied to the 3D beach evolution around a port in the field. Finally, the prediction method in the short-and long-term was discussed.
