Takaaki UDA, Masahisa Totsuka

Abstract

On the Numazu Ushibuse coast located south of Numazu City a headland was built as a measure against beach erosion and beach nourishment was carried out at the updrift side of the headland. Beach changes after the completion of the construction of this headland was observed by aerial photographying and characteristic beach changes around the headland was studied. A part of the nourished beach was largely deformed by littoral drift. A method which reduces further beach changes is proposed.
