บทคัดย่อ

Phan Thiet bay in VIetnam has eroded and accreted for many years. That causes serious consequences because main activities of community in Phan Thiet bay are tourism and fishery which depend on shoreline significantly. Not only the economy but also people’s life and environment are affected by erosion and accretion. Both natural factors and human factors may cause shoreline change such as waves, currents, structures along the coast or changing of sediment from river. This study aims to investigate the effect of jetties on shoreline in Phan Thiet bay, Binh Thuan, Vietnam by analyzing the Landsat satellite images by using Geographic Information System (GIS), and determining End Point Rate of shoreline change by Digital Shoreline Analysis System (DSAS). The result could be one source for an appropriate plan of coastal management in this area. The study found that after the Jetties were built in 1997 and 2004, the shoreline change rate was lower than that recent years from 2016 to 2020.
