Coastal Erosion in the Gulf of Thailand

Abstract

Shorelines in the Gulf of Thailand that have undergone extreme change (such as, the Chao Phraya River mouth and the east coast of the peninsula) have been studied through the analysis of available navigation and topographic maps, aerial photographs and satellite images to determine areas of erosion and accretion. Severe shoreline erosion can be found on the west of the Chao Phraya River mouth (−500 m), Phetchburi (−200 m) and Hua Hin (−100 m), while accretion can be found on the east of Chao Phraya River mouth and south of Songkhla Lagoon inlet. Active sand-spit migration at Bang Nara River mouth poses severe problem for navigation of fishing boats.KeywordsWave HeightRiver MouthSignificant Wave HeightCoastal ErosionNortheast MonsoonThese keywords were added by machine and not by the authors.
