Investigation of cliff recession along 20km of the West Wales coastline has recognised erosion processes and mechanisms. Mean contemporary recession rates of 13cm/year have been measured in glacial embayments where storm-wave action is considered the primary direct agent initiating cliff erosion. Morphological and field mapping evidence suggested that different mechanisms have produced recession in other areas, i.e. sub-aerial processes, marine exposure and rockfall activity.
