WebFigure 13.2. 1 Longshore currents are caused by waves approaching shore at a small angle, moving water parallel to the shore (Steven Earle, “Physical Geology”). Another important effect of waves reaching the shore at an angle is that when they wash up onto the beach, they do so at an angle, but when that same wave water washes back down the ... 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.
