An intensive field survey was carried out before and after a typhoon Goni at Anmok Beach, east coast of Korea, where a submerged breakwater exists. Survey items include offshore wave height, direction, and period; nearshore wave height, direction, and period, current and water level, bed load and suspended sediment load; bathymetry; and shoreline position. Interesting bathymetric change was observed after the typhoon: offshore sediment transport and consequent bathymetric change happened along the most coastline. The data exhibit the impact of the typhoon clearly, A wave-resolving numerical modelling system CST3D-WR was applied to the site for the typhoon situation, and qualitatively well reproduced the field bathymetric change.
