Comprehensive study on Energy Dissipation Performances of Two-layer Porous Energy Dissipation Plate

In this paper, we introduce a new type of two-layer porous energy dissipation plate breakwater, consisting of one upper porous plate and a lower plate. The system is used to control energy dissipation in breakwaters. The structure performance of dissipating waves has been investigated in detail in the regular wave tests. The factors identified with the characteristics of the energy dissipation plate are discussed, such as the relative width (B/L), the relative hole-size (A/A(0)) and the wave steepness (H/L). The comparison and analysis of the energy dissipation coefficients with respect to different factors are presented. Model test results indicate that the two-layer porous energy dissipation system is effective in dissipating a significant amount of wave energy.
