Abstract:
A method of forming an artificial reef unit under water on a base comprises the steps of:(1) locating a tube of a flexible material divided by dividing walls of a flexible material into an array of compartments or cells running the length of the tube, the compartments being arranged in rows and columns so that the tube divided by the dividing walls has a honeycomb structure, with a first end of the tube on the base and a second end of the tube above the first end of the tube and under water; (2) securing the tube in position on the base using one or more elements selected from the group consisting of flexible elements and rigid elements, attached to a fixed object; and (3) at least partially filling some or all of the compartments with a filler material so that at least some of the compartments are adjacent two or more other compartments filled with the filler material to support and be supported by the adjacent compartments; and wherein a side of the tube facing open water in use is profiled to dissipate wave energy by deflecting the waves.
