SEISMIC PROSPECTING METHOD APPLIED TO THE DETECTION OF OFFSHORE BREAKWATER UNITS SETTILING IN THE SEABED

 ´˜^i‰pjF
In solving a problem of offshore breakwater subsidence, it is important to investigate the shape of an existing breakwater whose crown has been repeatedly raised in the past. In this context, a series of observations were performed at the west coast of Niigata from 1984 to 1985, where seismic prospecting provided a reasonable estimate of breakwater cross sections under the water level as well as under the sea bottom.
