What is Alluvium

What is abrasion

what is Amenity value E.G beach
“Amenity value means how highly the beach are regarded by the community as part of the local landscape. This can be difficult to judge, but if a tree is large or otherwise distinctive and is at a location readily viewed by the public, it is of amenity value and should not be cleared.”
What is Attrition

What is Back shore
The back shore area of a beach extends from the limit of high water foam lines to dunes or extreme inland limit of the beach. It is only affected by waves during exceptional high tides or severe storms.
What is a barrier beach
a sand ridge that rises slightly above the surface of the sea and runs roughly parallel to the shore, from which it is separated by a lagoon. Examples from the Web for barrier beach.
what are Beach berms
A nearly horizontal plateau on the beach face or backshore, formed by the deposition of beach material by wave action, or by means of a mechanical plant as part of a beach recharge scheme
what are beach cusps

what is Beach nourishment

what is a blowhole
In geology, a blowhole is formed as sea caves grow landwards and upwards into vertical shafts and expose themselves towards the surface, which can result in blasts of water from the top of the blowhole if the geometry of the cave and blowhole and state of the weather are appropriate.
