A peresyp (пересыпь) or a bay-mouth bar [1] is a narrow sandbar that rises above the water level (like a spit) and separates a liman or a lagoon from the sea. Unlike tombolo bars, a peresyp seldom forms a contiguous strip and usually has one or several channels (called girlo ( гирло ) in Russian) that connect the liman and the sea.
Baymouth bar – low and narrow strip of alluvial land made from sand or pebbles; Beach – Area of loose particles at the edge of the sea or other body of water; Raised beach – Emergent coastal landform; Beach cusps – Shoreline formations made up of various grades of sediment in an arc pattern
A spit (cognate with the word for a rotisserie bar) or sandspit is a deposition bar or beach landform off coasts or lake shores. It develops in places where re-entrance occurs, such as at a cove's headlands, by the process of longshore drift by longshore currents. The drift occurs due to waves meeting the beach at an oblique angle, moving ...
The Doom Bar sand bank extends across the River Camel estuary in Cornwall, England, UK. A harbor or river bar is a sedimentary deposit formed at a harbor entrance or river mouth by the deposition of freshwater sediment or by the action of waves on the sea floor or on up-current beaches.
Longshore drift from longshore current is a geological process that consists of the transportation of sediments (clay, silt, pebbles, sand, shingle, shells) along a coast parallel to the shoreline, which is dependent on the angle of incoming wave direction. Oblique incoming wind squeezes water along the coast, generating a water current that ...
The Sandwich Town Neck beach project is the biggest in New England, preventing storm damage to neighborhoods, businesses, and the historic district.
List of shoals of Oregon contains all natural river bars, sandbars, spits, and shoals identified by the USGS in the U.S. state of Oregon.The USGS defines a bar as a "natural accumulation of sand, gravel, or alluvium forming an underwater or exposed embankment (ledge, reef, sandbar, shoal, spit)".
Sediment erosion and deposition dynamics in estuarine region, consequently the formation and growth of mouth bars, are affected by several natural and artificial factors. . Human activities, such as reservoir construction, large-scale reclamation and embankment construction completely disturb the hydrodynamic balance of the system and permanently interfere with the morphology of mouth bars.
