dc.description.abstract | Coastal areas in the equatorial Pacific island nations are being threatened by coastal erosion and flooding caused by the global climate change and sea level rise. Actually, 80% Coastal regions of Kosrae, Federated States of Micronesia have high exposure to the effect of coastal erosion. Survey on coastal geomorphology is important because it can serve as a direct indicator for sea level rise and be used in the basic data for coastal vulnerability analysis. In this study, the precise 3D topography using terrestrial LIDAR and total station was surveyed in Kosrae, Federated States of Micronesia, and vulnerable areas to floods were also analyzed by 3D terrain analysis. As a result, an average elevation of the intertidal zones, dykes, roads and residential areas were -0.2m, 2.4m, 2.6m and 1.9~2.4m above sea level, respectively. The elevation of the north and south coastal road was about 2.7m, while coastal road in central area located at estuary of the river was about 2.2m, and represented in the lowest elevation. An average elevation of central area in dyke was also 2.1m, and represented the lowest. The central area was analyzed as being high vulnerability to floods, given that the tide range of this area was 1.8m. Especially, flooding comes first in inland area located at estuary when assumed a simple sea level rise. It is due to low elevation, 1.4m. The elevation of the intertidal zone raised toward the south (average high exposure to the effect of coastal erosion.
