Longshore drift

Index Longshore drift

Longshore drift is a geological process that consists of the transportation of sediments (clay, silt, sand and shingle) along a coast parallel to the shoreline, which is dependent on oblique incoming wind direction. [1]

Angle

In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

Arcachon Bay

Arcachon Bay (in French, the Bassin d'Arcachon, and known locally simply as "le Bassin") is a bay of the Atlantic Ocean on the southwest coast of France, situated in Pays de Buch between the Côte d'Argent and the Côte des Landes, in the region of Aquitaine.

Groyne

A groyne is a rigid hydraulic structure built from an ocean shore (in coastal engineering) or from a bank (in rivers) that interrupts water flow and limits the movement of sediment.

Harbor

A harbor or harbour (see spelling differences; synonyms: wharves, haven) is a sheltered body of water where ships, boats, and barges can be docked.

Headland

A headland (or simply head) is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water.

Inlet

An inlet is an indentation of a shoreline, usually long and narrow, such as a small bay or arm, that often leads to an enclosed body of salt water, such as a sound, bay, lagoon, or marsh.

Intertidal zone

The intertidal zone, also known as the foreshore and seashore and sometimes referred to as the littoral zone, is the area that is above water at low tide and under water at high tide (in other words, the area between tide marks).

Kaitorete Spit

Kaitorete Spit is a long finger of land which extends along the coast of Canterbury in the South Island of New Zealand.

Ocean current

An ocean current is a seasonal directed movement of sea water generated by forces acting upon this mean flow, such as wind, the Coriolis effect, breaking waves, cabbing, temperature and salinity differences, while tides are caused by the gravitational pull of the Sun and Moon.

Port

A port is a maritime commercial facility which may comprise one or more wharves where ships may dock to load and discharge passengers and cargo.

Rakaia River

The Rakaia River is in the Canterbury Plains in New Zealand's South Island.

River

A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river.

River delta

A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water.

New!!: Longshore drift and River delta · See more »

Sediment

Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles.

Sedimentary budget

Sedimentary budgets are a coastal management tool used to analyze and describe the different sediment inputs (sources) and outputs (sinks) on the coasts, which is used to predict morphological change in any particular coastline over time.

Shear stress

A shear stress, often denoted by (Greek: tau), is the component of stress coplanar with a material cross section.

Storm surge

A storm surge, storm flood or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low pressure weather systems (such as tropical cyclones and strong extratropical cyclones), the severity of which is affected by the shallowness and orientation of the water body relative to storm path, as well as the timing of tides.
