    en.wikipedia.org/wiki/Tetrapod_(structure)

    A wave-dissipating concrete block is a naturally or manually interlocking concrete structure designed and employed to minimize the effects of wave action upon shores and shoreline structures, such as quays and jetties. One of the earliest designs is the Tetrapod, invented in 1950.

    Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.

    Open channel applications include bank stabilization, flow and grade control, scour protection for bridge piers, and biostabilization.The primary mechanism of protection employed is an increase in the relative roughness of the channel bank (as characterized by the Manning's Roughness Coefficient); the Manning's n is relatively high at 0.1.
