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.
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.
Tombolo near Karystos, Euboea, Greece Tombolo contrasted with other coastal landforms.. A tombolo is a sandy or shingle isthmus.A tombolo, from the Italian tombolo, meaning 'pillow' or 'cushion', and sometimes translated incorrectly as ayre (an ayre is a shingle beach of any kind), is a deposition landform by which an island becomes attached to the mainland by a narrow piece of land such as a ...
The barrier beaches that enclose bar-built estuaries have been developed in several ways: building up of offshore bars by wave action, in which sand from the seafloor is deposited in elongated bars parallel to the shoreline, reworking of sediment discharge from rivers by a wave, current, and wind action into beaches, overwash flats, and dunes,
The thickness of the deposit is around 120 m. [1] Fossil mollusca are abundant, and fossil fish are to be found, as well as Palaeophis, a sea-snake, and Puppigerus, a sea turtle. Nummulites and other foraminifera also occur. The Bracklesham Group lies between the Barton Clay above and the Bournemouth Beds, [citation needed] Lower Bagshot, below ...
