When an artificial beach is installed, the resistance of the artificial beach for ocean wave has been considered, but tidal current has not been considered. In this study, in order to clarify the relationship between morphological changes of artificial beach installed in the strait has strong tidal current, the present paper describes the results of field survey and numerical analysis. The main conclusions obtained in this study are summarized as follows: a) Tidal current fluctuates in semidiurnal period, but sea level fluctuates in semidiurnal or diurnal. b) Ebb current and flood current were different in maximum running speed. c) Spatially asymmetric patterns of ebb and flood may cause mass transport of both water and sediment in this area.
