Conf. Coastal. Eng. VL - 1 IS - 35 SE - Waves DO - 10.9753/icce.v35.waves.24 UR - https://icce-ojs-tamu.tdl.org/icce/article/view/8234 SP - waves.24 AB - The tsunami-height reduction using a very large floating structure, i.e., VLFS, is discussed, with the water waves, interacting with a floating thin-plate, simulated numerically. The final tsunami-height reduction rate increases, as VLFS length, VLFS flexural rigidity, or the wave height of an incident tsunami, is increased. If two VLFSs are utilized, the final tsunami-height reduction rate, also depends on the distance between the VLFSs. In two-dimensional tsunami propagation, another wave propagates to the outside, along the crest line of the main wave, leading to an additional tsunami-height reduction. ER -
