Theoretical solution of shoreline change was applied to the Kujukuri, Misawa and Fuji coasts, and the coefficient of littoral drift was evaluated and compared. Aerial photographs were read to investigate shoreline changes on the updrift side of Katakai fishery port on the Kujukuri coast, where southward littoral drift dominates. Observed shoreline changes were well explained by the theoretical solution. The same method was applied to the Misawa and Fuji coasts, and coefficient of littoral drift on each coast was compared.
