This study conducts a critical examination of the Longshore Sediment Transport Rate (LSTR) along Cua Can Beach in Phu Quoc City, Kien Giang Province. This notable pocket beach is characterized by its natural beauty and burgeoning tourist developments. The escalating construction of tourist facilities and resorts in close proximity to the shoreline, without considering beach morphological changes, poses a significant threat to the coastal integrity and sustainable development of the region. In response to this concern, our research aims to estimate the LSTR on the west coast of Phu Quoc to advocate for informed coastal engineering management and sustainable development strategies. Employing an integrated methodology that combines remote sensing with a simplistic one-line model, this study provides a comprehensive assessment of sediment dynamics along Cua Can Beach. The findings reveal consistent annual sediment transport from south to north, with an estimated quantity ranging from 5,000 to 20,000 m³ per year.
