[Plan]Monitoring Recovery of Coastal Forest in Sanriku Coast, Japan

Theme:
Monitoring Recovery of Coastal Forest in Sanriku Coast, Japan

Period:
3 months

Background:
Japan is an island nation surrounded by oceans. In order to protect inland area from coastal disasters caused by sea breezes, sand blow, high tides, and tsunamis, coastal forests are developed in large area. In Tohoku Region, a large area of coastal forests are suffered the great damage by 2011 Tohoku Tsunami. As a reconstruction, coastal areas have been developed to coastal forests in order to protect inland region from coastal disaster. This research aims to review distribution of damage on coastal forests by 2011 Tohoku Tsunami and monitors both natural and man-made recovery using Remote Sensing.

Method:
By calculating NDVI ratio between pre-tsunami image and post-tsunami image, a distribution of damage and seriousness of damage are output.
By calculating NDVI ratio between post-tsunami image and one-year-after-tsunami image, a distribution of recovery is output.

Expected Result:
Recovery patterns of coastal forest are analyzed with recovery process of each forest and damage seriousness.
