AN EXPERIMENTAL STUDY OF THE FLARING SHAPED SEAWALL APPLIED FOR ROAD SEAWALL IN THE NEIGHBORHOOD OF SHORELINE

Abstract

A Flaring Shaped Seawall (FSS) can make reduce crest height rather than conventional seawall in rough sea. However, the FSS has not been sufficiently made a study of application for road seawall in the neighborhood of shoreline.In order to clarifyt he hydraulic characteristics of the FSS as road seawall in that sea, two-dimensional wave experimentsw ere carried out, and wave run-uph eight, overtopping rate, pressured istribution and others were measured.It is confirmed that the characteristics of the FSS are more superiort o the verticalw all, and that are almost similar to the vertical wall protected with block mounds. So it is found that the FSS is suited to road seawall without wave-dissipating blocks.
