Research Abstract |
The study area is the central part of Tohoku District, facing the Pacific Ocean. Many mega-flood evidences and some debris flows are recognized on the coastal lowland and the adjacent area. Especially, many "Natural Levee and Abandoned Channel Systems" are distributed on the Sendai Coastal lowlands. The "Natural Levee and Abandoned Channel Systems" are the clear evidence of mega-flood events. In this study, the formative periods of "Natural Levee and Abandoned Channel Systems" and "Large scale Debris flows" were determined by radio carbon method. As the result, two periods, which mega-flood occurred at high frequency, ware determined. They ware 2600-2400 yrBP and 1600-1400yrBP.
