Long-term shoreline changes of the Yoshizaki coast located around a mouth of a tributary of the Suzuka River flowing into Ise Bay were investigated on the basis of the comparison of past geographical maps and aerial photographs. The characteristic height of beach changes was evaluated to be 4m from the bathymetric survey data. Longshore sand transport rate of 2×104m3/yr was obtained from the shoreline changes multiplied by this characteristic height of beach changes in the natural condition. In recent years, this longshore sand transport of the coast was totally exhausted and a long shoreline was separated into several pocket beaches.
