What causes Long Shore Drift (Littoral Drift )

Web27 de out. de 2024 · Landforms Deposited by Waves Longshore drift continually moves sand along the shore. Deposition occurs where the water motion slows. The smallest particles, such as silt and clay, are deposited away from shore. Waves also move sand from the beaches on shore to bars of sand offshore as the seasons change. WebLongshore currents are affected by the velocity and angle of a wave. When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in … rita heart
