A groyne gradually creates and maintains a wide area of beach on its updrift side by trapping the sediments suspended in the ocean current. This process is called accretion of sand and gravel or beach evolution. It reduces erosion on the other, i.e. downdrift, side by reducing the speed and power of the waves striking the shore.
A tombolo is a bar that forms an isthmus between an island or offshore rock and a mainland shore. In places of reentrance along a coastline (such as inlets , coves , rias, and bays), sediments carried by a longshore current will fall out where the current dissipates, forming a spit.
A shingle beach, also known as either a cobble beach or gravel beach, is a commonly narrow beach that is composed of coarse, loose, well-rounded, and waterworn gravel, called shingle. The gravel (shingle) typically consists of smooth, spheroidal to flattened, pebbles , cobbles , and sometimes small boulders , generally in the 20 to 200 ...
Collapsed Ordovician limestone bank showing coastal erosion.NW Osmussaar, Estonia.. Coastal geography is the study of the constantly changing region between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, climatology and oceanography) and the human geography (sociology and history) of the coast.
Asphalt and sandbag revetment with a geotextile filter. A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water and protect it from erosion.
I spent time along Florida's 30A in three towns: Seaside, Rosemary Beach, and Alys Beach. Each beach town was very different, and the one I liked best felt the most "Florida" to me.
Porto Covo, west coast of Portugal Seaside in Budelli, Italy. Budelli beach is famous for the color of its sand, which is pink due to the presence of fragments of a microorganism called Miniacina miniacea. [21] Tides often determine the range over which sediment is deposited or eroded. Areas with high tidal ranges allow waves to reach farther ...
