What is Backshore zone?
Backshore. The part of the beach lying between the beach face and coastline. The backshore is dry under normal conditions; it is often characterised by berms. The backshore is only exposed to waves under extreme events with high tide and storm surge.
What is a backshore in geology?
backshore The part of a beach that is above the level of normal high spring tides. This zone is usually dry; only when exceptionally high tides or storms occur does wave action influence this part of a beach.
What are Subaerial processes?
Sub-aerial process are land-based processes which alter the shape of the coastline. These are a combination of weathering and mass movement.
What are the essential features of the backshore?
The backshore typically features the material deposited by storm waves. The gradient of the beach tends to change during the year. Beaches are typically steeper in summer. This is because constructive waves are more common in summer, but destructive waves are more common in winter.
Where is the backshore on a beach?
The backshore is the region of the beach above the high tide line, which is only submerged under unusually high wave conditions, such as during storms. The foreshore lies between the high tide and low tide lines; it is submerged during high tide and is exposed during low tide.
What is a foreshore area?
foreshore area means the land between the foreshore building line and the mean high water mark of the nearest bay or river.
What is subaerial erosion in geography?
What is the difference between backshore and foreshore?
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. The backshore encompasses the area landward from the water’s reach at normal high tide to the maximum uprush during storms.
What is the meaning of backshore?
Definition of backshore. : the part of the seashore between the foreshore and the coastline covered by water only during storms of exceptional severity.
What is the meaning of shores?
[bak-shawr, -shohr] noun Geology. the zone of the shore or beach above the high-water line, acted upon only by severe storms or exceptionally high tides. the area immediately adjacent to a sea cliff.
What is the meaning of coastal zone?
the zone of the shore or beach above the high-water line, acted upon only by severe storms or exceptionally high tides. the area immediately adjacent to a sea cliff.
What is the definition of a storm beach?
: the part of the seashore between the foreshore and the coastline covered by water only during storms of exceptional severity.
