Abstract

Abstract A beachfront wave energy dissipation structure is disclosed. The structure has a plurality of vertically stacked parallel plates having two lateral edges, a shore-facing edge, and a water-facing edge, and a plurality of columns disposed between and connecting the plates. The columns are laterally and longitudinally distributed so as to impede free passage of waves between the plates. The shore-facing end of the bottom-most one of the plates preferably is supported at an angle in the range of 10 degrees to 30 degrees from the horizontal, so that the structure can be positioned with the plates angling upwardly away from the water. The plates reduce in longitudinal dimension from the bottom to the top of the stack, and are arranged in step fashion rising in the direction away from the water-facing edge.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 66 words
A beachfront wave energy dissipation structure, comprising a plurality of spaced-apart vertically stacked parallel plates each having two lateral edges, a shore-facing edge, and a water-facing edge, and a plurality of columns disposed between and connecting said plates, said columns being laterally and longitudinally distributed over a substantial portion of the area between said plates so as to impede free passage of waves between said plates.
Claim 2
Dependent Claim 66 words
A beachfront wave energy dissipation structure, comprising a plurality of spaced-apart vertically stacked parallel plates each having two lateral edges, a shore-facing edge, and a water-facing edge, and a plurality of columns disposed between and connecting said plates, said columns being laterally and longitudinally distributed over a substantial portion of the area between said plates so as to impede free passage of waves between said plates.
Claim 3
Dependent Claim 53 words
A structure as recited in claim 1, further comprising means for supporting the shore-facing end of the bottom-most one of said plates at an angle in the range of 10 degrees to 30 degees from the horizontal, whereby said structure may be arranged such that said plates angle upwardly away from the water.
Claim 4
Dependent Claim 39 words
A structure as recited in claim 2, in which said plates reduce in longitudinal dimension from the bottom to the top of the stack, and are arranged in step fashion rising in the direction away from the water-facing edge.
Claim 5
Dependent Claim 23 words
A structure as recited in claim 1, in which said columns occupy at least about 15 percent of the volume between respective plates.
Claim 6
Dependent Claim 23 words
A structure as recited in claim 2, in which said columns occupy at least about 15 percent of the volume between respective plates.
Claim 7
Dependent Claim 23 words
A structure as recited in claim 3, in which said columns occupy at least about 15 percent of the volume between respective plates.
