Erosion energy in the coastal and estuarial environment is substantially greater than that encountered inland. Traditionally, layers of large stone or riprap have been used for coastal protection as they provide a rough surface to dissipate erosion energy. Encapsulating stones within gabions or mattresses thereby stopping it moving, increases the resistance of the revetment, and is a more efficient use of imported stone. Encapsulated stone mattresses also often have added ecological value.
