How does longshore drift happen
WebLongshore drift: the movement of pebbles along a beach by oblique waves. Longshore drift has a sorting effect on the horizontal distribution of beach materials. Where cliffs are exposed to strong wave action, the shore is usually strewn with boulders too large to be moved by the waves. WebLongshore currents are affected by the velocity and angle of a wave. When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. …
