PURPOSE:To effectively dissipate waves of long wavelength, by a method wherein plural columns, having a sloped wall adapted to collect incoming waves, are filled upright in a lower hull having buoyancy. CONSTITUTION:Plural columns 3 are filled upright at proper intervals in a lower hull 2 serving as buoyance for a wave dissipating weir 1, and a side wall 4 of the column 3 is formed so as to collect incoming waves 5 and have a sloped angle theta. A porous panel 6 is located in a position in the vicinity of a portion where a distance between the columns 5 is narrowed to minimum (l), and a platform 8 is installed to the top parts of each column 3 and the porous plate 6. Location of this floating wave dissipating weir causes the incoming waves 5 to be accelerated by means of the slope wall 4 of the column 3 and run to the porous panel 6, and when the waves run through the porous panel, a viscous effect is increased to produce a sufficient wave dissipating effect. This enables effective dissipation of waves of a long wavelength. |
