Seawall A seawall is a form of coastal defence constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a sea wall is to protect areas of human habitation, conservation and leisure activities from the action of tides, waves, or tsunamis. As a seawall is a static feature it will conflict with the dynamic nature of the coast and impede the exchange of sediment between land and sea. The shoreline is part of the coastal interface which is e

Continental shelf The continental shelf is an underwater landmass which extends from a continent, resulting in an area of relatively shallow water known as a shelf sea.Much of the shelves were exposed during glacial periods and interglacial periods.The shelf surrounding an island is known as an insular shelf.The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope followed by the flatter continental rise.Sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope, called the continental rise.he shelf surrounding an island is known as an insular shelf.

Coast Salish These Salish Defensive Sites are rock wall features constructed by Coast Salish peoples. One was excavated by Kisha Supernant in 2008 at Yale, British Columbia. The functions of these features may have included defense, fishing platforms, and creation of house terraces.

Wall The Wall stretches for 300 miles and is approximately 700 feet tall, It is made of solid ice and stone, and can be seen for miles round. It appears grey or blue depending on the weather and time of day.The top is wide enough for a dozen mounted knights to ride abreast and it is thicker at the base.pproximately 300 miles in length and 700 feet in height, the Wall is protected by the Night's Watch and according to some, ancient spells and sorcery.

Sea Clouds White Sea Edit. The White Sea (白海, Haku-kai) is the lower part of sky ocean, located 7000 meters above the Blue Sea, comprised of Sea Cloud. It also had strange, rubbery clouds that bounce objects off of them and can be used as trampolines for those who are creative. There are different ways to get to the White Sea from the Blue Sea.

- Barrier islands are detached linear islands of sand and/or gravel(rare) that run parallel to the shore and are back by a bay, lagoon, marsh, or tidal flat. Barrier islands are wave and wind built landforms and form in wave dominated or mixed energy environments, typically microtidal or mesotidal environments.

Definitions &Translations The term  coastal zone  is a region where interaction of the sea and land processes occurs. Both the terms coast and coastal are often used to describe a geographic location or region; for example, New Zealand's West Coast, or the East and West Coasts of the United States.A pelagic coast refers to a coast which fronts the open ocean, as opposed to a more sheltered coast in a gulf or bay.A shore, on the other hand, can refer to parts of the land which adjoin any large body of water, including oceans (sea shore) and lakes (lake shore). pelagic coast refers to a coast which fronts the open ocean, as opposed to a more sheltered coast in a gulf or bay.

- Background: The intertidal zone is the area where land and sea meet. This habitat is covered with water at high tide, and exposed to air at low tide. The land in this zone can be rocky, sandy or covered in mudflats.The intertidal zone is divided into several zones, starting near dry land with the splash zone, an area that is usually dry, and moving down to the littoral zone, which is usually underwater.he land in this zone can be rocky, sandy or covered in mudflats.

Sea Caves, Arches, Stacks and stumps Sea Caves, Arches, Stacks and stumps. Edit 0 20 …. Sea caves. A sea cave, also known as a littoral cave, is a type of cave formed primarily by the wave action of the sea. The primary process involved is erosion. Sea caves are found throughout the world, actively forming along present coastlines and as relict sea caves on former coastlines.

Seawalls Seawalls are hard engineered structures with a primary function to prevent further erosion of the shoreline. They are built parallel to the shore and aim to hold or prevent sliding of the soil, while providing protection from wave action (UNFCCC, 1999).

South Devon Railway sea wall A First Great Western train on the sea wall approaching Teignmouth. The South Devon Railway sea wall is situated on the south coast of Devon in England. A footpath runs alongside the railway between Dawlish Warren and Dawlish, and another footpath forms a continuation to the sea front promenade at Teignmouth.Both these form part of the South West Coast Path.he South Devon Railway was built to the designs of Isambard Kingdom Brunel and takes a route from Exeter which follows the River Exe to Dawlish Warren, runs beneath the sea cliffs to Teignmouth, and then follows the River Teign to Newton Abbot. It follows tidal waters for about 13 miles, 4 of which are open sea.

- Barrier Islands. Barrier islands are typically thin strips of sandy beaches on the ocean side, with a line of sand dunes in the middle and a salt-water marsh between the dunes and a lagoon/bay. A maritime forest may grow behind the dunes, if the island is wide enough. Barrier islands are constantly re-shaped by storms. Overwash fans develop when waves breach the dunes, carrying sand inland and depositing it at flood tide behind the dunes - sometimes covering the maritime forest or marsh with a layer of fresh sand, but often filling some of the open water in the bay/lagoon.

Seawall A seawall (or sea wall) is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. seawall works by reflecting incident wave energy back into the sea, thereby reducing the energy and erosion which the coastline would otherwise be subjected to. In addition to their unsightly visual appearance, two specific weaknesses of seawalls exist.

- Areas known for large concentrations of sea caves include the Pacific coast states of the USA (Alaska, Washington, Oregon, and California, and especially, California's Channel Islands); the Na Pali coast of Kauai; the Greek Isles; the British Isles, and many other places with cliffs of good solid rock to host the caves.egions where sea caves form are often associated with arches and sea stacks. Often these are remnants from collapses of sea caves, and in some cases may line up along what had been a fault line in a rock unit that has been carved by the sea into isolated stacks of rock.

Seawall In some cases piles are placed in front of the wall to lessen wave energy slightly. 1  The first implemented, most easily designed and constructed type of seawall. 2  Vertical sea walls deflect wave energy away from the coast. 3  Loose rubble can absorb wave energy.
