Uda, T., Serizawa, M., & Miyahara, S. (2018). DEVELOPMENT OF SAND BARS AROUND ISLANDS OFFSHORE OF KRABI IN THAILAND AND THEIR PREDICTION. Coastal Engineering Proceedings, 1(36), papers.22.


Poda and Po Da Nok Islands are located offshore of Krabi facing the Andaman Sea in the south part of Thailand. A shallow sea extends together with the development of a slender sandbar between these islands, and there is another small island named Tup Island connected by sandy beach. Sandbars can well develop in this area because of the shallow sea. The wave-sheltering effect of these islands affect to another island. On August 2016, field observation was carried out to study the formation of sandbars, and numerical simulation using the BG model was carried out to investigate the interaction of three islands.
