Abstract
We have estimated the annual variation and vertical structure of residual current with two-year long observed flows using AWAC, an acoustic wave and current meter, in two locations of Haeundae coastal waters with mean water depth of about 15m and 22 m. We have also measured short-term flows near the surf zone during in summer and winter. The moving average method with fortnightly period was applied to estimate speed and direction of the residual current. The wave data measured by using AWAC has been analyzed to estimate the seasonal variation of wave environment in the Haeundae coastal waters.In this study, we have estimated the seasonal variability of wave and residual current using long-term observed current and wave data measured by bottom mounted AWAC. The variation of Haeundae sand budget can be traced by the estimated ROMS-SWAN nearshore current. This measured hydrodynamic data will be used for the validation of operational coastal modeling system for the prediction of hydrodynamics and sediment transport in Haeundae coastal waters for supporting the development of coastal erosion control system.5m and 22 m.
