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.

本研究针对泰国三座主要突堤（jetty）开展沿岸净输沙量研究，涉及差安突堤、克拉突堤及那沙通突堤。本次调查于2019年8月、2019年9月、2020年8月及2020年9月开展。野外调查采用实时动态差分（Real Time Kinematic, RTK）技术测量海岸高程。针对每座突堤南侧2公里岸线开展海岸高程勘测，各海滩剖面的布设间距为25米。为覆盖潮上带与潮间带区域，每条海滩剖面的最高点设置于海滩沙丘处，最低点则设定为相对于国家平均海平面的-0.5米高程。
