Abstract
Abstract A fluid wave energy dissipating and absorbing structure having at least one surface exposed to fluid wave action, said surface comprising an array of alternating three-sided pyramidal protuberances and triangular flat spaces, said protuberances and spaces being alternating in both rows and columns. Erosion caused by fluid wave action may be prevented or mitigated by erecting on a surface subject to such erosion a fluid wave energy dissipating and absorbing structure, and forming on said structure at least one surface exposed to the eroding fluid wave action, said surface comprising an array of alternating three-sided pyramidal protuberances and triangular flat spaces as above described.
