| Research Abstract |
Objective of this research is to clarify the formation and evolution of micro landforms of the riverine coastal plains in relation to the sedimentary environments in late Holocene. Detail analysis of the micro landforms and the sediments were done on the Nobi plain. Evolution of the plain was clarified in relation to the distribution of archaeological sites in the plain, and it is clarified that the landforms of the plain developed not in order but step by step according to the change of deposition area. Change of the river course and deposition area was also studied in relation to the buried forest in the Yahagi river lowland.
Detail micro landform and its relation to the flooding were studied in the upper stream of the Mekong River delta in Cambodia. Coastal change and evolution of mangroves were also studied in the northeastern Mekong River delta. Mangrove peat can be seen in the area around 50-80 km inland from the present coastline and the ages of them are 6000-7000 cal BR After 6000 cal BP, deposition of fluvial sediments covered mangroves and formed fluvial landforms in the area.
Effects of the micro landforms to the flooding and tsunami disaster were also studied especially on the case of the tsunami disaster caused by the giant earthquake off Smatra on December 26, 2004. Run up and back wash tsunami flows were distinguished in the Nam Khem coastal plain, Thailand. Thick tsunami deposits in the plain are seen in the depression as swales between the ridges.
