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.
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.
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.
Bay – Recessed, coastal body of water connected to an ocean or lake; Baymouth bar – low and narrow strip of alluvial land made from sand or pebbles; Bayou – Body of water in flat, low-lying areas; Beach – Area of loose particles at the edge of the sea or other body of water
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 lagoon is separated from Great Pond Bay on its southern side by a vegetated baymouth bar about 1,100 m long, with a maximum width of 105 m. It connects with the sea by a narrow channel at its south-eastern corner. The perimeter of the lagoon is vegetated with black mangroves, and extensive mudflats are exposed when water levels are low. The ...
Nov. 30—Except for the oil and natural gas themselves, one of the oilfield's hottest commodities these days is the sand used to fracture or "frac" the bedrock formations and loosen them up for ...
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 ).
