Abstract

Nobiru Coast, which is 2.8 km long coast located in Miyagi Prefecture, Japan, is a well-known coast because of high sediment deposition rate (Figure 1). The predominant littoral drift of this coast is from east to west (Takahashi and Tanaka, 2005). The sediment deposit at the western end causes significant effect on the aquaculture in Matsushima Bay which is located on the right of Miyato Island, due to closure of a channel connecting open sea and Matsushima Bay. Tanaka et al. (2006) reported the sediment deposition rate on this coast from historical maps. The tsunami, which occurred on 11 March 2011, caused different types of damage on the left and right-hand sides of the coast. Accordingly, this study would evaluate the change of shoreline on Nobiru Coast at decadal to centennial scales including the 2011 tsunami impact using aerial and satellites images.
