What’s shoreline armoring?

Shoreline armoring along Wells Beach, Maine.

Shoreline armoring alongside Wells Seashore, Maine. Coastal managers and property house owners typically try and stabilize coastal land and shield residential and business infrastructure alongside the coast by constructing shoreline armoring buildings to carry again the ocean and forestall the lack of sediment.


Coastal erosion—the lack of shoreline sediment – is a fancy course of that constantly reshapes the shoreline and may threaten coastal property. With roughly 350,000 buildings situated inside 500 ft of the nation’s shoreline, erosion is an issue many U.S. coastal communities should handle.

Coastal managers and property house owners typically try and stabilize coastal land and shield residential and business infrastructure alongside the coast by constructing shoreline armoring buildings to carry again the ocean and forestall the lack of sediment. Examples of such buildings are seawalls, breakwaters, and riprap.

Shoreline armoring has each helpful and detrimental results. Armored shorelines can stop sandy seashores, wetlands, and different intertidal areas from transferring inland because the land erodes or sea ranges rise, however in addition they have the potential to get rid of habitat for marine organisms and seaside entrance for the general public by proscribing the pure motion of sediments. The important thing to shoreline stabilization, whether it is required, is to make use of a site-specific stabilization technique that balances the wants of the general public and the wants of the pure system.

Whereas coastal erosion is a pure course of, the speed of erosion may be drastically influenced by human actions. Pure components that contribute to erosion embody sediment provide; geologic traits; adjustments in sea degree; and the consequences of waves, currents, tides, and wind—all of which differ by location. Human actions that may alter pure shoreline processes embody seaside nourishment (including sand), dredging of ports and coastal approaches, development of harbors and sediment-trapping dams, and the use of shoreline armor.
