On the Study of Practical Application of Long-Period Wave Absorption Structure

We have developed the long-period wave absorption structure by the experimental studies. On planning to apply it to actual fields, we propose the advanced type structure adding to upright wave absorbing blocks to dissipate not only long-period waves but also short-period one. The hydraulic performance such as reflection rates is verified through experiments. Furthermore, we reproduce the hydraulic performance of the structure with the numerical analysis based on the non-linear shallow water theory and demonstrate that it is useful for practical design of the structures.
