CONSIDERATIONS ON FORESHORE SLOPESAND ON-OFFSHORE MOVEMENTS OF BARS INFLUENCING ON BEACH PROFILES OF THE TOMAKOMAI COAST.

Abstract

 The foreshore slope influencing on the beach profile was considered by using the sounding data at the Tomakomai coast of Hokkaido on the Pacific Ocean. As the result, it was clear that the bar height was influenced by the foreshore slope, the return flow and the incident wave length. Moreover, the relation between the bar height and the return flow was classified by the foreshore slope and the incident wavelength.
