Recently rip currents are frequently observed in the summer at the beaches located along the East Sea coast. To understand the generation types of rip currents occurred at the Ease Sea beaches, numerical simulations of rip currents over the topographies of the Sokcho, Naksan, Gyeongpo, Mangsang beaches were performed by using a Boussinesq-type wave and current model, FUNWAVE. The offshore and nearshore topographically-controlled rip currents and the transient rip currents were well reproduced due to the alongshore non-uniformities involving the phase interaction effects. This study looked over the generation types of rip currents to occur at the beaches with complicated field bathymetries.

The tidal and meteorological condition associated with wintertime surges in the Ease China Sea are described. The vertically-integrated finite difference model of the East china Sea have been used to investigate the surges generated during a period of 5 days in November, 1983 dynamically. Computed residual elevations are compared with hourly records form selected tide gauges along the west coast of Korea. Preliminary results on circulation pattern derived from the numerical model are presented and discussed. Further refinement of the model using current meter observation is presently being performed to provide more accurate information on bottom stress distribution.
