Description

Beach changes of the Akiya coast located on the western shore of Miura Peninsula were investigated. Comparison of aerial photographs and analysis of shoreline changes were carried out. It was found that sand movement to wave shadow zone of the fishing port is the main cause of the beach erosion of this coast, as well as decrease in fluvial sand supply from the rivers. Erosion rate was determined from the difference of the colors attached to the seawall.
