ABSTRACT Yoon, B.I. and Woo, S.B., 2013. Tidal asymmetry and flood/ebb dominance around the Yeomha channel in the Han River Estuary, South Korea In: Conley, D.C., Masselink, G., Russell, P.E. and O'Hare, T.J. (eds.) Several field measurements were conducted to study the characteristic of tidal asymmetry and flood/ebb dominance in the Han River Estuary (HRE), Gyeonggi Bay (GGB) on the western coast of Korea. Tidal currents at this area were simultaneously measured at four stations during the winter season, and previously observed tidal data were analyzed. The HRE is macro-tidal coastal zone with a mean depth less than 12m and a tidal range varying 3.5 (neap) to 8.0m (spring). The tidal amplitude to depth ratio is large enough to generate non-linearity in the tidal wave. The relative phases (2M2-M4) are represented flood dominant using harmonic constants from previously observed tidal data. However, there exists a limitation to apply this kind of method for tidal asymmetry to an area in which freshwater dis...
