Abstract
A method predicting predominant wave direction to a pocket beach from the asymmetry in the configuration of the pocket beach is shown. The method is applied to the coastline in Kyoto Prefecture facing the Sea of Japan. In total the shape of ten pocket beaches is compared and it is shown that predicted wave directions agree well. In addition beach changes in a pocket beach due to seasonal changes in wave direction is also studied through the comparison of aerial photos and sounding maps.
