摘要：

Haeundae Beach is sandy beach at Busan, Korea. Haeundae Beach is about 1.5 km long enclosed by two headlands. The normal direction of the beach is between south and south-east. Tidal current at the site is not negligible, and waves are relatively high during monsoon and winter seasons. Currents were measured at nine points along Haeundae Beach on 4 June 2008 by using GPS-equipped drogues. Bathymetry around Haeundae Beach was surveyed on 7 August 2007 and 12 November 2007 by using an echo-sounder; wave, tide, and tidal current were measured between the two survey days, so that bathymetric change at the beach was obtained from the two surveys. The measured current vectors may include wave induced current element, tidal current element, and wind-induced current. Seasonal sediment transport pattern at Haeundae Beach, Busan, Korea is known to be simple, according to previous observation. Typically sediment moves eastward, while sediment moves westward in winter. Tidal current contributes to long-term bathymetric change at the beach by transporting small-sized sediment.
