Abstract


The aim of this paper is to investigate experimentally and numerically the breaking limit, breaking and post-breaking wave deformation due to three different types of submerged structures such as bottom-seated, non-bottomseated fixed and tautly-moored structures. Based on laboratory experiments, the breaking limits have been formulated for three different types of the submerged structures. Moreover, a modified SOLA-VOF method with the nonreflective wave generation method has been proposed and found to be very effective in evaluating the wave breaking process and post-breaking wave characteristics.

Keywords
