［Abstract］

　To evaluate the influences of sea-level rise on deltas and coastal lagoon geological and geographical study were conducted in the Satun Lowland, Lake Songkhla and Chao Phraya Delta of Thailand and the Mekong Delta of Vietnam. Moreover multi-temporal analysis using SAR images of J-ERS-1 between 1992 and 1997 were applied for understanding of changes of land use and the shoreline in coastal areas of Thailand.
　These results indicated that past sea-level rise of the order of l0s cm impacted seriously on coastal areas in Thailand. Particularly coastal erosion is one of key issues we must concern in the assessment of the future sea-level rise.
