Net longshore sediment transport at jetties along the Gulf of Thailand

This research focused on net alongshore sediment transport at 3 major jetties in Thailand, being Cha Am jetty, Krai jetty, and Na Saton jetty. The survey was conducted in August 2019, September 2019, August 2020, and September 2020. The field investigations measured coastal elevation by Real Time Kinematic (RTK) technique. The coastal level along 2-km shoreline south from each jetty was surveyed with each beach profile being spaced 25 m apart. In order to cover the sub-aerial and intertidal zones, the uppermost point of each beach profile was set at a beach dune, while the lowermost point was set at an elevation of -0.5 m from national mean sea level.
