Accropode (1981) The Accropode is a single-layer artificial armour unit developed by Sogreah in 1981. Accropode concrete armour units are applied in a single layer. Ecopode (1996) The Ecopode armour unit with a rock-like appearance was developed by Sogreah to enhance the natural appearance of concrete armourings above low water level.
Tetrapods on Graciosa Island, Azores Tetrapods in Latvia Tetrapods protecting a marina on Crete, Greece.. A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters.
Large Xblocs (8.0 m 3 or 280 cu ft) on a trial placement area. An Xbloc is a wave-dissipating concrete block (or "armour unit") designed to protect shores, harbour walls, seawalls, breakwaters and other coastal structures from the direct impact of incoming waves.

Riprap causes morphological changes in the riverbeds they surround. One such change is the reduction of sediment settlement in the river channel, which can lead to scouring of the river bed as well as coarser sediment particles.
An akmon is a multi-ton concrete block used for breakwater and seawall armouring. [1] ... This page was last edited on 23 July 2024, at 14:12 (UTC).
For example, rock can weigh between 150-175 lb; [2] a suitable rip-rap boulder comparable to a 96 inch A-Jacks unit (about 36 c.f.) would weigh about 5800 pounds, about 16% more than the A-Jacks unit. A-Jacks also have the advantage of being interlocking and self-stabilizing.
This equation was rewritten as follows in the nineties: = () / where: H s is the design significant wave height at the toe of the structure (m); Δ is the dimensionless relative buoyant density of rock, i.e. (ρ r / ρ w - 1) = around 1.58 for granite in sea water
