Wave-Cut Cliff Landscape
Reference work entry
This is a landscape consisting of steep cliffs on a rocky coast carved by marine erosion and gravitational collapse along joints or bedding. The formation process is as follows. The slope near the shore is steep and is subject to wave action. Waves carrying debris and gravels wash against the slope, scouring and eroding the cliff surface and forming wave-cut notches at the cliff base. Through repeated wave action, the notches expand inwards, and the upper rock eventually collapses, forming a steep cliff. This process continues and results in further retreat of the coast. Before the collapsed debris at the wave-cut cliff base is washed away by waves, it can protect the coast from waves for a certain period of time. However, when the debris is moved away by waves, coastal erosional resumes. However, following the widening of the wave-cut platform and building up of accumulated debris in the water, the wave action is restricted, and, the cliff recession rate decreases or even stops.
