| Abstract: | Incident waves reflecting normally from a breakwater produce standing waves; they are more conducive in terms of scouring of the seabed than the action of progressive waves. Employing Biot's theory of consolidation, the pore pressure response within a porous seabed induced by the standing wave is analytically presented. Experiments for the response are also conducted in a wave flume. Unlike the progressive wave, the variation of standing-wave induced soil response is temporal and spatial. The theories compare well with the experiments. |
