| Outline of Final Research Achievements |
In the modern shorelines and archaeological sites, I studied erosion and deposition in coastal lowlands by storm surge and overwash processes of typhoon. Sediments of modern spit in Matsunase coast, Mie Prefecture, is recognized in constructive and destructive phases by overwashs of typhoons. This is different from the tsunami deposits of catastrophic destruction.Coastal deposits of archaeological sites in the western Osaka Plain at Kofun period preserve sedimentation from typhoon processes. Cross-stratified longshore bar deposits show landward-fining facies, and commonly climb up the planar-stratified foreshore deposits. This suggests that bar growth and landward migration was most significant during waning stage of storm-waves. Growth of beach ridges due to sand transport to higher position by typhoon was important role of development and extension of the plain.
