Kim, K.H. and Shim, K.T., 2014. A field investigation of waves and wave-induced currents at the Youngrang Coast of the Republic of Korea.
An accurate identification of the root cause of beach erosion should be taken in the precedence over designing reliable countermeasures. This study reviews the characteristics of the wave-induced currents by using the observation results on wave and current. The observed patterns were taken from comprehensive observation results which studied characteristics of wave and wave induced current as well as suspended load and bed load. The observations were conducted at the Youngrang Coast in the east coast of Korea. Based on the field observation results, Youngrang Coast has intermittently shown the occurrence of high waves due to winter monsoons. Affected by the high waves, the wave-induced currents have shown to exist inside the wave-breaking zone with a current velocity of 0.5–1 m/s. Such strong wave-induced currents are considered to be acting the main source of winter longshore sediment transport and beach erosion.
