A breakwater structure is designed to absorb the energy of the waves that hit it, either by using mass (e.g. with caissons), or by using a revetment slope (e.g. with rock or concrete armour units). In coastal engineering , a revetment is a land-backed structure whilst a breakwater is a sea-backed structure (i.e. water on both sides).
A jetty is a man-made structure that protrudes from land out into water. A jetty may serve as a breakwater , as a walkway, or both; or, in pairs, as a means of constricting a channel. The term derives from the French word jetée , "thrown", signifying something thrown out.

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.
A mole is a massive structure, usually of stone, used as a pier, breakwater, or a causeway separating two bodies of water. A mole may have a wooden structure built on top of it that resembles a wooden pier. The defining feature of a mole, however, is that water cannot freely flow underneath it, unlike a true pier.
The breakwater closure was finally completed in 1898. [3] An iron pier was built beginning in 1871 by the U.S. Army Corps of Engineers and completed in 1882. The 1,700-foot (520 m) pier was designed to carry rail traffic directly out to ships in the harbor. The structure used iron screw piles with wood decking. The pier was later adapted for ...
