ABSTRACT:
A system for alleviating scouring damage at the base of a structure anchored in the bed of a body of liquid flowing at a velocity relative to the structure, such as a bridge pier in a river bed, comprises a plurality of hollow vehicle tires surrounding the structure in a matrix of plural stacks of tires connected together with their toroidal axes substantially aligned. Each stack comprises a predetermined number of tires so that the top surface of the matrix forms a predetermined angle relative to horizontal.
