Longshore drift no longer transports materials along this section of the coast. The construction of the rock groynes has created a larger, higher sandy beach for Mappleton. This means that even at high tide waves do not reach the base of the cliffs along the seafront at Mappleton and the erosion has slowed to a point
beach to the south of Mappleton but is not replenished as it is trapped by defences at Mappleton. As the result of this the beaches to the south have very little sediment and during low tide expose a combination of sand and clay boulders that have been eroded from the cliffs.
