the process in which beach sediment move down a beach with the current
Beach sediment
A spit is formed due to the process of the long shore drift, the waves approach the beach in the direction of the prevailing winds, this causes the sediment to be pushed up the beach at an angle.
longshore drift
Longshore drift is the process of sediment moving along a beach due to wave action. It is driven by the longshore current, which is a current that flows parallel to the shoreline. Therefore, longshore drift is the result or effect of a longshore current.
effect. longshore drift is the combined effect of sediments moved by longshore currents and and beach drift. longshore currents are ocean currents that flow parallel to the coast while beach drift is the resultant zigzag movement along the beach.
Longshore drift causes sand to move along a beach further down (or up) the coast. This in effect causes beach erosion. If a hotel has a beach in front of it, one can assume that visitors to the hotel may use that stretch of beach to sunbathe etc. If the beach gets eroded, the sand may be of a poorer quality or even inaccessible if there is a wall to climb over and down etc. This means the beach would have to be fed each year with sand from further down the coast or groynes put in place to trap the sand.
