BEACH CHANGES AROUND ARTIFICIAL HEADLANDS ON ICHINOMIYA COAST

Abstract

  On the Ichinomiya coast located in the south part of Kujukuri Beach, ten artificial headlands have been constructed since 1983. By 2010, part of these headlands has been completed but the rest of them are still under construction. The shape of these headlands is classified into T-shaped and jetty-type, and characteristic beach changes occurred around these headlands depending on their shape. The shoreline changes around these artificial headlands were investigated on the basis of the aerial photographs, and typical shoreline changes were summarized.
