| Rising sea levels and longshore drift since the ice age have created a remarkable, 500 km-long beach. |
|
| Find animations and images showing a variety of depositional landforms resulting from longshore drift. |
|
| This process is called longshore drift and is generated by wave and current action. |
|
| This process is repeated and pebbles gradually shift along the beach, a process called longshore drift. |
|
| As part of the restructure, artificial headlands were built to hold the sand and prevent longshore drift. |
|
| Due to input of sediment from rivers, marine deltas may form, due to beach and longshore drift such features as spits, bay barriers, and tombolos may form. |
|
| When wave trains impinge obliquely on a beach, a net flow of water, called a longshore drift, occurs parallel to the beach. |
|
| In natural conditions marginal deltaic coasts benefit from sediment input from upcoast deltas via longshore drift and current-driven transport. |
|
| Linear, prograding coasts are the consequence of a substantial supply of sediment derived by transport along the coast by longshore drift and coastal currents. |
|
| At the southern margin, longshore drift induced by the southeasterly winds accumulated carbonate sands and gravel in a spit-platform, at the lee side of a protruding cape. |
|
| The majority of tidal inlets on longshore drift shores accumulate sediment in flood and ebb shoals. |
|
| Most revetments do not significantly interfere with transport of longshore drift. |
|
| The sand bars were formed naturally by the longshore drift of sand. |
|
| He says the EDF and Environment Agency proposals are short-sighted and won't provide any long-term defence against the longshore drift that affects the stretch of coast from Kent into East Sussex. |
|
| When sea-level rise decelerated, deltaic sedimentation and longshore drift gradually landlocked the islands, transforming the archipelago into a peninsula. |
|
| The model was initially designed to simulate sediment transport by longshore drift from south-westerly swells but was later adapted to also simulate south-south-easterly swells. |
|
| There are numerous calculations that take into consideration the factors that produce longshore drift. |
|
| These formulas all provide a different view into the processes that generate longshore drift. |
|
| This sediment then enters the coastal system and is transported by longshore drift. |
|
| Spits occur when longshore drift reaches a section of headland where the turn is greater than 30 degrees. |
|
|
|
| The terminal groyne prevents longshore drift from bringing material to other nearby places. |
|
| This can be used to build up beaches suffering from beach starvation or erosion from longshore drift. |
|
| It stops the movement of the original beach material through longshore drift and retains a natural look to the beach. |
|
| The water transported the eroded deposits north and south along the outer Cape's shoreline through a process known as longshore drift. |
|
| The wave pattern created by this water movement causes a convergence of longshore drift on the opposite side of the island. |
|
| The transportation of sand southward along the Atlantic Coast of Florida by longshore drift ends in the area of the Safety Valve. |
|
| Waves and wave-driven currents cause longshore drift of sand along the beach and offshore. |
|
| The creation of ports and harbours throughout the world can seriously impact on the natural course of longshore drift. |
|
| Not only do ports and harbours pose a threat to longshore drift in the short term, they also pose a threat to shoreline evolution. |
|
| One onlooker, who wishes to remain anonymous, said the sand pumped ashore on the beach is already being washed away by the process of longshore drift. |
|
| The impact of longshore drift sediments on this inlet system is highly influenced by the variation in the number of lagoon entrances and the location of these entrances. |
|
| These banks may slowly migrate along the coast in the direction of the longshore drift, alternately protecting and exposing parts of the coastline. |
|
| For example, the Arcachon lagoon is a tidal inlet system in South west France, which provides large sources and sinks for longshore drift sediments. |
|
| As an example, the creation of a port in Timaru, New Zealand in the late 19th century led to a significant change in the longshore drift along the South Canterbury coastline. |
|
| As an example, the New Brighton spit in Canterbury, New Zealand, was created by longshore drift of sediment from the Waimakariri River to the north. |
|
| Longshore drift transported sediment from this eroding rocky coastline to these embayments following the culmination of the post-glacial marine transgression some 7 ka ago. |
|
| Longshore drift is simply the sediment moved by the longshore current. |
