| Outline of Final Research Achievements |
The 2011 Tohoku-oki Earthquake Tsunami altered coastal landforms. Reportedly, it caused remarkable coastal erosion. To elucidate the processes of recovery from the tsunami event, the authors have monitored coastal landform changes through interpretation of sequential topography maps based on measurements by high-resolution GPS in field surveys and aerial photogrammetry. Results of this study clarify that the coastal landforms of invested area have recovered approximately 60-80% in volume compared to the volume eroded by the tsunami, and the sediments for the recovery have been supplied from upstream of coastal drift.
