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 ...
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. Where beaches are suitably mobile, or the river's suspended or bed loads are large enough, deposition can build up a sandbar that completely ...
The Sandwich Town Neck beach project is the biggest in New England, preventing storm damage to neighborhoods, businesses, and the historic district.
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.
A bar in a river is an elevated region of sediment (such as sand or gravel) that has been deposited by the flow. Types of bars include mid-channel bars (also called braid bars and common in braided rivers ), point bars (common in meandering rivers ), and mouth bars (common in river deltas ).
A point bar is an area of deposition where as a cut bank is an area of erosion. Point bars are formed as the secondary flow of the stream sweeps and rolls sand, gravel and small stones laterally across the floor of the stream and up the shallow sloping floor of the point bar.
