Rocky revetment at a restoration site along Keene Creek, Duluth, Minnesota. Spring 1994.
Revetments are structures placed on banks or cliffs in such a way as to absorb the energy of incoming water or explosives. They are usually built to preserve the existing uses of the shoreline and to protect the slope, as defense against bombs or artillery, or to secure an area from stored explosives.

Sea Revetments
Like seawalls, revetments armor and protect the land behind them. They may be either watertight, covering the slope completely, or porous, to allow water to filter through after the wave energy has been dissipated. Seawall protecting homes from storm waves and beach erosion. ...
Most revetments do not significantly interfere with transport of littoral drift. They do not redirect wave energy to vulnerable unprotected areas, although beaches in front of steep revetments are prone to erosion. Materials eroded from the slope before construction of a revetment may have nourished a neighboring area, however. Accelerated erosion there after the revetment is built can be controlled with a beach-building or beach-protecting structure such as a groyne or a breakwater.

A revetment is a type of structure that is built along an embankment, shoreline or steep facing slope in order to protect it against erosion generated by wave or current action.
Revetments have been built along the shorelines of many lakes, rivers and oceans to protect a water-shoreline interface from excessive erosion (such as between the CKD pile and Lake Huron).
The revetment should not be seen as a permanent solution to the problem of bulk movement of CKD material into Lake Huron, given that the revetment has a limited life span.
