Contributing Factors of Longshore Transport: Beach Drift & Longshore

WebThis process, known as longshore drift, can move huge quantities of material over great distances. On a suitable beach, this can be quite easy to see for yourself using brightly painted stones. Drift of sediments along beaches is also assisted by longshore currents … WebFig.3 shows that a single groyne, long or short, causes downdrift erosion on a shoreline exposed to a slightly oblique wave climate. In order to extend the length of the protected area, and to compensate for the lee side erosion, it is common practice to construct several groynes along the shoreline, a so-called groyne field. fitness home trainingWebThe groynes trap sediment transported by longshore drift, providing a wide sandy beach.This provides effective protection from destructive waves.
