Tóm tắt

This study investigates long-term shoreline changes at My Khe Beach in central Vietnam using satellite-derived data and the open-source toolkit CoastSat. By analysing shoreline positions from 1989 to 2025 across 26 transects, the research identifies patterns of erosion and accretion, with recent trends showing widespread shoreline retreat and localised beach growth near newly constructed coastal infrastructure. Monthly averaged shoreline data were used to reduce bias from uneven satellite coverage, and linear trend analysis was applied to assess shoreline movement over time. The findings highlight the spatial and temporal variability of shoreline dynamics and demonstrate the potential of remote sensing tools for coastal monitoring in data-scarce regions. This study provides valuable insights for coastal management and emphasises the need for further validation using ground-based survey data to improve accuracy and support sustainable planning across Vietnam’s vulnerable shoreline zones.
