Abstract
The coastal area of the Sendai coast was suffered expensive damage from the tsunami that followed the Great East Japan Earthquake in March 2011. In the case of a large-scale disaster, monitoring the recovery process over the long term will contribute largely to improving the efficiency of shortening the disaster recovery period and readjustment of the disaster recovery plan. In this study, the recovery and reconstruction process of coastal embankments and reconstruction roads and coastal woods on the Sendai plains were evaluated using high-resolution satellite images of five periods with superior characteristics for time series and high-detailed investigation. In addition, we evaluated the change process of the vegetation environment and the land cover characteristics in the coastal area by the change process of the normalized vegetation index by using high-resolution spectral characteristics. It was considered that this monitoring methods was effectively used from these results to evaluate the long-term and continuous change processes in large-scale disaster.
