Park, D.; Kim, H.; Lee, S.; Lee, J., and Yoo, J., 2018. Simulation of storm-induced cross-shore sediment transport at Anmok Beach with wave-resolving CST3D-WR. In: Shim, J.-S.; Chun, I., and Lim, H.S. (eds.), Proceedings from the International Coastal Symposium (ICS) 2018 (Busan, Republic of Korea). Journal of Coastal Research, Special Issue No. 85, pp. 1001–1005. Coconut Creek (Florida), ISSN 0749-0208. 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.
