WebLongshore drift is the process of sediment transportation across a beach. It is dependent on the prevailing wind which affects the waves and as a result the swash (waves up the beach). Sediment is transported with swash at a 45 degree angle up the beach and 90 degree angle back to the sea with backwash.
