Why Stop Natural Erosion
Shoreline erosion is a natural occurrence because beaches are not static dumps of sand. Rather, the sand on shorelines is constantly being moved by water currents.
When developers and property owners build something on a shore, a static structure is introduced onto a moving surface. When this happens, the natural process of erosion generally has to be controlled to protect the stability of the static structure, such as a building or road.
Another reason to control the flow of shoreline water is to simply control the amount of sand deposited onto a beach.
Types of Erosion Prevention Structures
Seawalls and BulkheadsSeawalls are built to protect roads and buildings near a coast. They can be constructed with concrete, steel, boulders or wood, and they run parallel to the beach at the land/water interface. A popular seawall in the Gulf Coast is the Galveston Seawall, atop of which runs a major throughway stretching across the Galveston Island coast.
Seawalls in certain applications are also referred to as bulkheads or revetments. They protect static coastal structures such as roads and buildings by impeding the movement of sand otherwise naturally caused by the water.
Seawalls stop natural landward erosion of shorelines. Thus, they can be used to artificially sustain a beach. Seawalls can even be designed to temporarily hold back ocean waters during hurricanes and other storms. In fact, the Galveston Seawall was built for this very purpose after the Galveston Hurricane of 1900.
GroinsGroins are another type of breakwater that are perpendicular, rather than parallel, to the shoreline. They can be built of steel, concrete or wood, and they are designed to break up and trap the longshore flow of sand. Where groins are constructed, the sand builds up on one side and decreases on the other side.
For beaches whose current is in a constant direction all year, a groin “steals” sand that would otherwise deposit onto the shore. This keeps the amount of sand on a beach constant all year long, while transferring the erosion further down the beach.
BreakwatersBreakwaters consist of large piles of rocks laid parallel to the shore. Breakwaters are generally used to calm waters for harbors and artificial marinas. When a breakwater lays below the surface of the water, it is referred to as a submerged breakwater. These are used to reduce beach erosion and are also called artificial “reefs.”
Jetties are extensive, man-made piles of boulders or concrete, larger than groins, and constructed on either side of a coastal inlet. In contrast to groins which are built to alter beach erosion, jetties create a channel to the ocean for the purposes of navigation.
