A follow-up computation of the hydraulic model experiment of Noguchi et al. (2015) was conducted by three-dimensional coastal current and beach change model. The numerical model reproduced the experimental outputs of current and beach changes around the artificial reef system to confirm the applicability of the model which consists of SWAN for wave computation, POM for three-dimensional coastal current field, and the Van del Werf sediment transport formulation under wave and current coexisting field. The calculation results reproduced the surface and bottom layer current patterns around the artificial reef and the velocities relatively well. Although the topographic change calculation has a problem in the reproducibility of the sedimentation near the shoreline, a certain amount of topographic change tendency can be reproduced in the case of a high incident wave. It was confirmed that the three-dimensional beach current and beach deformation model had generally good applicability.
