A beach is a landform alongside a body of water which consists of loose particles. The particles composing a beach are typically made from rock, such as sand, gravel, shingle, pebbles, etc., or biological sources, such as mollusc shells or coralline algae. Sediments settle in different densities and structures, depending on the local wave action and weather, creating different textures, colors and gradients or layers of material.
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. The landward retreat of the shoreline can be measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural.
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.
Landforms are categorized by characteristic physical attributes such as their creating process, shape, elevation, slope, orientation, rock exposure, and soil type.
Barrier islands are coastal landforms and a type of dune system that are exceptionally flat or lumpy areas of sand that form by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish. A barrier chain may extend uninterrupted for over a hundred kilometers, excepting the tidal inlets that separate the islands, the longest and widest being Padre Island of Texas, United States. Sometimes an important inlet may close permanently, transforming an island into a peninsula, thus creating a barrier peninsula, often including a beach, barrier beach. The length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, sediment supply, sea-level trends, and basement controls. The amount of vegetation on the barrier has a large impact on the height and evolution of the island.

Beach nourishment describes a process by which sediment, usually sand, lost through longshore drift or erosion is replaced from other sources. A wider beach can reduce storm damage to coastal structures by dissipating energy across the surf zone, protecting upland structures and infrastructure from storm surges, tsunamis and unusually high tides. Beach nourishment is typically part of a larger integrated coastal zone management aimed at coastal defense. Nourishment is typically a repetitive process since it does not remove the physical forces that cause erosion but simply mitigates their effects.
Inverloch is a seaside town located in Victoria, Australia and the most populous city of the Bass Coast Shire. It is located 143 kilometres (89 mi) south east of Melbourne via the South Gippsland Highway on the Bass Highway in the Bass Coast Shire of Gippsland, Victoria, Australia. Known originally for the calm waters of Anderson Inlet, it is now also known for the discovery of Australia's first dinosaur bone.
Anglesea is a town in Victoria, Australia. It is located on the Great Ocean Road in the Surf Coast Shire local government area. In the 2016 census, Anglesea had a population of 2,545 people.
Wye River is a small town in Victoria, Australia. It is also the name given to the waterway which flows through the town and into the sea at this point. Situated some 155 km west of Melbourne, on the Otway Coast part of the scenic Great Ocean Road, the Wye River township is a popular tourist destination about 15 km west of the resort town of Lorne, Victoria. It became a popular place for Melburnians to holiday after the Great Ocean Road was officially opened in 1932. The postcode of Wye River is 3234. At the 2016 census, Wye River had a permanent population of 66 although its holiday population is ten times that number.
The Ash Wednesday Storm of 1962 occurred on March 5–9, 1962 along the mid-Atlantic coast of the United States. Also known as the Great March Storm of 1962, it was considered by the U.S. Geological Survey to be one of the most destructive storms ever to affect the mid-Atlantic states. Classified as a level 5 or Extreme Nor'easter by the Dolan-Davis scale for classification of Atlantic Nor'easters it was one of the ten worst storms in the United States in the 20th century. It lingered through five high tides over a three-day period, killing 40 people, injuring over 1,000, and causing hundreds of millions in property damage in six states. The storm also deposited significant snowfall over the Southeast, with a regional snowfall index of 12.663.
Crescent Head is a town on the Tasman Sea coast, 340 km north-northeast of Sydney, in Kempsey Shire, New South Wales, Australia. At the 2011 census, Crescent Head had a population of 1,586 people. Its major industries include tourism and fishing. It has a 6-hole golf course overlooking the sea.
Djursland is a 44 km × 33 km hilly lowland peninsula in Denmark at the entrance to the Baltic Sea, between Denmark and Sweden in Northern Europe. Djursland protrudes into the Kattegat sea, as part of the larger peninsula of Jutland, which itself extends from the Central European continent. Djursland comprises the two municipalities of Norddjurs and Syddjurs.
Shoalwater Bay Military Training Area is a heritage-listed military installation at Byfield Road, Byfield, Shire of Livingstone, Queensland, Australia. It is a large, relatively undisturbed and intact natural system with a wide variety of coastal landforms and a high level of biodiversity. It contains a diverse range of marine and coastal wetland landscapes, vegetation types and ecosystems. It was added to the Australian Commonwealth Heritage List on 22 June 2004.
Beach evolution occurs at the shoreline where sea, lake or river water is eroding the land. Beaches exist where sand accumulated from centuries-old, recurrent processes that erode rocky and sedimentary material into sand deposits. River deltas deposit silt from upriver, accreting at the river's outlet to extend lake or ocean shorelines. Catastrophic events such as tsunamis, hurricanes, and storm surges accelerate beach erosion.
MacKerricher State Park is a state park in California in the United States. It is located 3 miles (4.8 km) north of Fort Bragg in Mendocino County. It covers 9 miles (14 km) of coastline and contains several types of coastal habitat, including beaches, dunes, headlands, coves, wetlands, tide pools, forest, and a freshwater lake.
Cable Beach is a 22 km (14 mi) stretch of white sand beach on the eastern Indian Ocean and the name of the surrounding suburb in Broome, Western Australia. Cable Beach was named after the telegraph cable laid between Broome and Java in 1889. Low cliffs of red ochre rise behind the very flat and wide beach, with waves that are mostly gentle in the dry season from May to October. In 2016, the population was 5,436.
Culham Inlet is an inlet located in the Goldfields-Esperance region of Western Australia. The inlet is also referred to as a coastal salt lake or a transient estuary, as the sand bar that prevents it discharging is almost always closed. The wetlands formed by the system are DIWA listed due to their ecological significance.
The January 1992 nor'easter was the second in a series of nor'easters in a 14-month period that produced strong winds, high tides, and flooding along the East Coast of the United States. It was a small, short-lived storm that was poorly forecast, intensifying rapidly on January 4 before striking the Eastern Shore of Virginia. The strongest quadrant of the storm moved over Delaware, and winds in the state reached 58 mph (93 km/h). The nor'easter weakened as it moved westward, and it dissipated over Virginia before the energy reformed and redeveloped offshore.
