LONG-TERM BEACH CHANGES OF NORTHERN KUJUKURI BEACH BETWEEN IIOKA AND KATAKAI FISHING PORTS

Abstract

 Beach changes of northern Kujukuri Beach were investigated on the basis of the aerial photographs. The shoreline positions and the seaward marginal line of the coastal forest, which had advanced seaward by excess planting of pine trees, were read and the beach width between them was calculated and compared. It was found that the beach width in this area rapidly decreased. Aerial photographs of the regions where severe beach erosion occurred were closely compared.
