Wave attenuation characteristics of a wave suppress system

A floating breakwater named Wave Suppress System (WSS-GEN-1) was previously developed to arrest the destructive power of water waves. It was experimentally proven to be an effective energy dissipater for scattering the energy of prevailing waves mainly through breaking, turbulence and friction; howe...
