3D Morphodynamic Model for Sandy Beach with Shore Reef

Abstract

This study is concerned with the development of a 3D morphodynamic model to sandy beach with shore reef such as exposed rock. The morphodynamics with exposion and buring of the shore reef are reproduced by advection and diffusion model for suspended sediment concentration. Firstly, some model tests were carried out in order to investigate the performance of the presented model. Secondly, the applicability of the presented model was investigated by comparing with the results of sounding survey conducted at sandy beach with shore reef around Sakenotsu fishing port, which is suffering from sedimentation.
