説明
Recovery of sandy beach from severe erosion by the 2011 tsunami can be observed on Sendai Coast even 3 years after the tsunami. The long-term effect of such a severe morphology change on sediment transport system is investigated through analysis of aerial photographs. Empirical Orthogonal Function (EOF) analysis is applied to shoreline positions extracted from the aerial photographs. The first and third modes express the recovery process of shoreline from the severe erosion with respective time-scale, and the superposition of their contribution rate is more than 70%. Comparison of shoreline change rate before and after the tsunami clearly shows that the recovery process of severely eroded area caused completely different trend of sediment transport processes.
