ABSTRACT

In this study, we analyzed the morphological changes on beach before and after the Typhoon Soulik using UAS (Unmanned Aerial System) based DoD (DEM of Difference). The morphological changes of beach were explained using DoD results, weather and marine data. As a result, a slight volume reduction of about 60 m3 were detected. Even with days of high wave height and wind speed, low tidal height during the period caused slight morphological changes on beach. Berm and cusp were developed around 3 m above mean sea level, under low wave height environment during the study period. In conclusion, morphological changes of Pado-ri beach by Typhoon Soulik were insignificant.
