#Water drift where to series#
The longshore trough as it applies to the area of coastlines can be defined as an elongate depression or series of depressions extending along the lower beach or in the offshore zone inside the breakers.ĭuring this drift sediment, the prevailing wind, which is the direction of the wind that it commonly blows in, moves waves carrying sediment that contains sand gravel and small particles that are found on the seabed into the beach at an angle. The backwash carries material back down the beach at right angles. The waves moving up the beach carries material up and along the beach are called the Swash. A Longshore Drift happens when waves move towards the coast at angles. Longshore drift is a coastal process that happens along the beach. Natural beach and shoreline erosion along wind and ocean tides constantly change coastlines along with ocean warming and the manmade developments that can make these natural processes happen even faster not always for the good. Current & sediment movement occurs in the surf zone & is also called Beach Drift. Longshore Drift, a geological process caused by currents & wave action moving at angles towards the shore carrying sediments like sand parallel to the shoreline is dependent on the prevailing incoming wind direction. Wind and ocean currents play an important part in Longshore Drift which causes beach erosion by stripping down a beach and moving total beaches to other locations taking with it the environment and wildlife that live there.
