SHORELINE CHANGE ANALYSIS AT TANINTHARYI, MYANMAR BY LAND-WATER BOUNDARY DETECTION ON SATELLITE IMAGES

抄録

 This study employs the satellite optical and SAR data to investigate the shoreline change at Tanintharyi coast, Myanmar, which is a typical fast-developing region in Southeast Asia. Successful extraction of the shoreline position indicates that satellite remote sensing is a powerful tool to monitor the coastal area, especially in data-insufficient regions. Long-term shoreline change analyzed from the optical satellite data shows that large evolution occurs at the river mouth. Annual shoreline change derived from the Sentinel-1 SAR data shows that the shoreline at the river mouther moves forth and back repeatedly after the construction of the small seaport. Quantitive evaluation of the impact due to the construction of the seaport needs more data such as rainfall and river discharge.
