A Living shoreline is a relatively new approach for addressing shoreline erosion and protecting marsh areas. Unlike traditional structures such as bulkheads or seawalls that worsen erosion, living shorelines incorporate as many natural elements as possible which create more effective buffers in absorbing wave energy and protecting against ...
While bulkheads may serve their purpose to slow erosion at a bluff or beachfront, they commonly cause a domino effect of change to the beach profile. The increased wave reflection caused by their presence can result in an increased re-suspension of sand in the water in front of the bulkhead.

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.
The Ballantine scale is a biologically defined scale for measuring the degree of exposure level of wave action on a rocky shore. Devised in 1961 by W. J. Ballantine, then at the zoology department of Queen Mary University of London, London, U.K., the scale is based on the observation that where shoreline species are concerned "Different species growing on rocky shores require different degrees ...
Brise-soleil can comprise a variety of permanent sun-shading structures, ranging from the simple patterned concrete walls popularized by Le Corbusier in the Palace of Assembly [3] to the elaborate wing-like mechanism devised by Santiago Calatrava for the Milwaukee Art Museum [4] or the mechanical, pattern-creating devices of the Institut du Monde Arabe by Jean Nouvel.
Barra da Tijuca – Rio de Janeiro. Breakwaters reduce the intensity of wave action in inshore waters and thereby provide safe harbourage. Breakwaters may also be small structures designed to protect a gently sloping beach to reduce coastal erosion; they are placed 100–300 feet (30–90 m) offshore in relatively shallow water.
One of the earliest mentions of groynes is in connection with the planned improvements to the silted-up Dover harbour, by one Fernando Poyntz in 1582. [3] [4] [5]In 1713 the first wooden groyne to protect Brighton's seafront and coastline was built, which had been heavily damaged in the Great storm of 1703, and again in 1705. [6]
