초록
This study analyzed morphological changes and sediment characteristics of three gravel beaches on Dokdo. We measured seven beach profiles and grain size at each profile. Among them, area of two beaches were found to increase and grow from north to south by aerial photo analysis. The reason of temporal change was related to wave deformation after construction of dock at Dongdo. The shape of gravel spit which deposit from cliff to sea at Seodo was changed following wind direction from north to south, and vice versa. The last influence on the shape of gravel spit guessed the No. 15 typhoon named Goni because the direction of 1st, 2nd berm and beach face was facing to southward. Three berms were observed at the profiles from a far distance dock, while only fair-weather berms were at the profiles which were least influenced from wind. Sediment size increased as the distance drifts farther away from shoreline, but the size decreased at middle of the profiles.
Abstract
This study analyzed morphological changes and sediment characteristics of three gravel beaches on Dokdo. We measured seven beach profiles and grain size at each profile.

The reason of temporal change was related to wave deformation after construction of dock at Dongdo. The shape of gravel spit which deposit from cliff to sea at Seodo was changed following wind direction from north to south, and vice versa. The last influence on the shape of gravel spit guessed the No. 15 typhoon named Goni because the direction of 1st, 2nd berm and beach face was facing to southward. Three berms were observed at the profiles from a far distance dock, while only fair-weather berms were at the profiles which were least influenced from wind. Sediment size increased as the distance drifts farther away from shoreline, but the size decreased at middle of the profiles.
