Foreshore: The area between the high tide and the low tide mark. Backshore: The area above the high tide mark, affected by wave action only during major storm events. What is a foreshore in geography? Beside the sea, a lake, or a wide river, the foreshore is the part of the shore which is between the highest and lowest points reached by the water.
What is the difference between backshore and foreshore?
is that backshore is (geology) an upper shore zone above high-tide while foreshore is the part of a shore between high water and low water, especially the beach exposed at maximum ebb spring tides. Other Comparisons: What's the difference?
What is the meaning of backshore?
The part of the beach lying between the beach face and the front dune, cliff base, vegetation line or coastal protection structure. The backshore is dry under normal conditions; it is often characterised by berms. Vegetation is generally sparse or even absent.
What is the difference between a backshore and a bar?
The backshore is only exposed to waves under extreme events with high tide and storm surge. Elongated sand body created by (tidal) currents or by waves . Bars in estuaries and tidal lagoons develop naturally in flow convergence zones, often in relation with channel meandering. Estuarine bars also occur where ebb- and flood-dominated channels meet.
What is the difference between the foreshore and the subtidal zone?
In the image above this area is recognized as the foreshore or beachface. Subtidal zone: consists of regularly submerged, relatively shallow water area seaward of the intertidal zone.

What is the backshore area?
Definition of Backshore: The part of the beach lying between the beach face and the dune foot or the coastline.
What separates the foreshore from the backshore?
bermThe foreshore is often separated from the backshore by a berm. A scarp may be present in the foreshore at the height of the most recent high tide.
What is the foreshore of a beach?
The foreshore can be said to be the part of the shore/beach, which is wet due to the varying tide and wave run-up under normal conditions, i.e., excluding the impact of extreme storm waves and storm surge.
What is the backshore in geology?
Backshore definition The area of a shore that lies between the average high tide mark and the vegetation. The backshore is affected by waves only during severe storms. (geology) An upper shore zone above high-tide. noun.
What are the two types of coastlines?
Shorelines can be generally divided into two types, high relief erosional shorelines and low relief depositional shorelines. Beach ridges are wave deposited sand ridges running parallel to shoreline. A wave-cut scarp is a steep bank created by wave erosion.
How is the backshore formed?
a nearly horizontal plateau on the beach face or backshore, formed by the deposition of beach material. A wave that has become so steep that the crest of the wave topples forward, moving faster than the main body of the wave. The still water depth at the point where the wave breaks.
What is the difference between foreshore and beach?
A beach can be divided into three regions; nearshore, foreshore , and backshore. The nearshore is always underwater, while the foreshore is that part of the beach extending from the mean low water line to the highest elevation reached by waves at normal high tide.
What does the word foreshore mean?
1 : a strip of land margining a body of water. 2 : the part of a seashore between high-water and low-water marks.
Who owns the foreshore?
the Crown EstateThe confusion may arise from the fact that the Crown Estate is the prima facie owner of all foreshore (and seabed) by virtue of prerogative right. This, in effect, means that the Crown Estate owns all of the foreshore unless it has in the past sold it or given it away.
What is the difference between littoral and coastal?
Coastal animals include sea lions, birds, jellyfish, dolphins, crabs, cockles, mussels, sea stars, etc. If an animal is on the shore of a river, lake, or ocean, it is littoral. If an animal is described as a littoral crab, it means that it lives on the shore of a river, lake, or ocean. Right on the shore line.
What is a beach zone?
Related Definitions Beach Zone means the area extending seaward from the seaward toe of the primary dune (vegetation line) or bulkhead line, as shown on the Department's CoastalVulnerability Assessment Maps.
What is littoral zone in geography?
littoral zone, marine ecological realm that experiences the effects of tidal and longshore currents and breaking waves to a depth of 5 to 10 metres (16 to 33 feet) below the low-tide level, depending on the intensity of storm waves.
What is beach berm?
A beach berm is a nearly horizontal shore parallel ridge formed on the beach due to the landward transport of the coarsest fraction of the beach material by the wave uprush (swash). This is the common definition for Beach berm, other definitions can be discussed in the article.
What is a shore profile?
A field exercise examining. beach topography and coastal processes. Overview: Working in teams, students conduct topographic surveys (beach profiles) using a pair of Emery rods (profile poles), a metric tape, and a sight level to accurately survey a shore from the foredunes to the waterline.
What are swash zones?
The swash zone is located at the landward edge of the surf zone on the upper part of the beach profile that is subjected to inundation (Fig. 8.1A). It is where incoming surf zone waves force oscillatory motion of the shoreline (land–sea boundary) at a variety of frequencies, typically greater than 0.003 Hz.
What is a beach zone?
Related Definitions Beach Zone means the area extending seaward from the seaward toe of the primary dune (vegetation line) or bulkhead line, as shown on the Department's CoastalVulnerability Assessment Maps.

Geography Vocabulary: GCSE Coasts
GCSE COASTS VOCABULARY. Abrasion: wearing away of cliffs by sediment flung by breaking waves.See Corrasion.. Angle of Dip: the angle of the bedding planes which affects the shape of the cliff. If the rock layers are horizontal, small overhangs of more resistant rock form in the cliff face.
As nouns the difference between backshore and foreshore
is that backshore is (geology) an upper shore zone above high-tide while foreshore is the part of a shore between high water and low water, especially the beach exposed at maximum ebb spring tides.
English
The part of a shore between high water and low water, especially the beach exposed at maximum ebb spring tides.
What is shoreline management?
The act of dealing – in a planned way – with actual and potential coastal erosion and its relation to planned or existing development activities on the coast, see Shoreline management. The objectives of Shoreline Management are:
What is coastal erosion?
Coast erosion is the process of wearing away material from the coastal profile due to imbalance in the supply and export of material from a certain section. Distinction must be made between incidental coastal erosion and ongoing coastal erosion.
Is the seafloor flat?
Bed forms. The seafloor is seldom flat, but generally undulated by the interaction with currents and waves . Undulated bedforms exist over a large range of spatial scales, from centimeters up to kilometers, see: Wave ripples, Wave ripple formation, Sand ridges in shelf seas, Stability models.
What is nearshore geology?
From a coastal geologist's morphological perspective, each of these has a unique definition, where the: nearshore is a broad classification defined as the region extending from the land water interface (shoreline) to a location just beyond where the waves are breaking,
What is the concept of nearshore, beach, and dunes?
For many of you, the concept of the nearshore, beach, and dunes probably conjures ideas such as swimming about in breaking waves, games of Frisbee on a sandy surface, or heavily vegetated mounds of sediment that have to be crossed in order to reach the beach.
What is beach zone?
beach is defined as the zone of unconsolidated material that extends landward from the low water line to a place where there is a marked change in physiographic form or a line of permanent vegetation representing dunes,
