Abstract:

Effects of tide on variation of beach profile are examined experimentally. It is clarified that tidal effect appears differently when it acts on beach of different profiles. Namely, in case of summer profile, tide tends to move berm position onshore. In case of winter profile, tide tends to change position and size of bar-trough system due to movement of breaking point.
