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.
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.
In addition to longshore bars discussed above that are relatively small features of a beach, the term shoal can be applied to larger geological units that form off a coastline as part of the process of coastal erosion, such as spits and baymouth bars that form across the front of embayments and rias.
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 design relied on data from the Beach Protection Authority to prevent it becoming a baymouth bar connecting to South Stradbroke Island. [13] Construction of the project had six main phases: retaining walls using approximately one million tonnes of imported rock; dredging 4.5 million cubic metres sand [10] closure of the old entrance
Baymouth bars built by prevailing winds and currents have created a significant number of lagoons and sheltered harbors, mostly near (but not limited to) Prince Edward County, Ontario, and the easternmost shores.
There are two theories with regard to the formation of Point Pelee. Firstly, it is thought that Point Pelee has formed from depositional processes. [10] Alternatively, it is suggested that Point Pelee is a relic of a past feature that has eroded over time. [10] This gap in knowledge provides the opportunity for further research.
