WebWave-cut platforms. Coasts of erosion form as a result of high energy waves, large fetch, high exposure and limited deposition. They are also associated with drift alligned coasts that are influenced by longshore drift. This transfer of sediment along the coast limits the development of beaches and leads to greater cliff exposure, hence cliff ... WebGroynes. Groynes are wooden barriers constructed at right angles to the beach to retain the material. The beach material, including sand and pebbles, are trapped between groynes and cannot be transported away by longshore drift.Groynes encourage a wide beach which helps absorb energy from waves, reducing the rate of cliff erosion. WebTransportation. Sediment is carried by the waves along the coastline. The movement of the material is known as longshore drift.
