Implications of littoral drift
WitrynaLittoral transport is the term used for the transport of non-cohesive sediments, i.e. mainly sand, in the littoral zone along a shoreline mainly due to the action of breaking waves. The littoral transport is also called the longshore transport or the littoral drift.. Description. Littoral transport is often described under the assumption that the … Witryna27 wrz 2024 · Beach drift and the longshore current contribute to the longshore transport, which is the movement of sand and sediment parallel to the coastline. …

Longshore drift from longshore current is a geological process that consists of the transportation of sediments (clay, silt, pebbles, sand, shingle) along a coast parallel to the shoreline, which is dependent on the angle incoming wave direction. Oblique incoming wind squeezes water along the coast, and so generates a water current which moves parallel to the coast. Longshore drift i…

Witryna8 lis 2024 · Conventionally, long-term coastline evolution is usually described using the diffusion equation. Particularly, the diffusion coefficient, ε, is a function of the wave angle: this implies that the diffusivity can assume negative values when wave angles are >45°.
