영문 초록

This study analyses wave characteristics of the northeastern coast of Korea, specifically in the areas of GangNeung, Yang-yang, Sokcho, and GoSung during typhoon Hinnamnor, which ranked as the 4th in the biggest damage caused. Measured wave data was collected from five different locations and analysed, revealing the maximum wave height in the decreasing order of DongHae>GangNeung>W-2>GoSung>W-1 hence displaying a trend of decreasing wave height as the wave approaches the coast. During the impact of typhoon, the measured wave data suggests that the wave directions were between ENE~E direction. This indicates that the waves developed in the South had minimal effect whereas wind waves of North-east direction were dominant. The analysis of measured wave data confirms that during the impact of Typhoon Hinnamnor in the Northern Region of the East Sea, the maximum wave height ranged between 2.2 to 3.8 meters, with an ENE to E wave direction. Although the incoming wave height during the typhoon was smaller than that of winter storms, it still impacted the shoreline for over 24 hours with wave heights exceeding 1.5 meters. Moreover, it was equivalent to the top 5 to 11% of wave heights during winter storms.
