Abstract

The 2011 Great East Japan Earthquake and Tsunami was one of the most catastrophic natural disasters that took place in Japan, caused significant changes to the sandy coasts. The destruction focused directly on the estuarine and coastal area in Miyagi Prefecture on which many river mouths are located. The severity of the damage to the morphology of these river mouths is likely comparable but the recovery of each reflects different process. This study, by collecting adequately photographs from various sources, provides a comprehensive view of the recovery process at four different river mouths in Miyagi Prefecture: Abukuma, Natori, Naruse and Kitakami Rivers. Over 8 years, some areas had their own potential to self-recover; however, some were under a poor recovering situation that formed an almost unchanged shape and required human endorsement to recover.
