Reinstate the failing tidal defence levee on a wide outside meander. Sediment accretions on the opposing point bar were acumulating as fast as the flood bank retreated, thereby threatening significant areas of farming land and infrastructure in the tidal flood plain.
                                                    

Cain Bio-Engineering designed and installed a contoured   brushwood mattress, anchored with hardwood stakes. Sediment deposited during each tidal cycle rapidly filled the mattress interstices with re-constituted clay colloid. The anaerobic conditions indefinately suspend decomposition of the internal woody skeleton, thus assuring the long-term integrity of the structure.

Structural life expectancy is well in excess of 100 years irrespective of rising sea levels..
