WebHow is cliff morphology influenced by the permeability of rock? For example: cliffs which have impermeable rock overlying permeable rocks limit percolation and therefore are more stable, preventing mass movement. Whereas, cliffs in which permeable rock overlies impermeable rock, water may soak into the cliff, making slope failure more likely as ... WebFeb 10, 2016 · The rate of cliff retreat depends on the frequency and severity of these events, but is also influenced by the resistance and structure of the outcropping formations, tide range and the presence of a rocky shore or shore platform that affords protection to the cliff base.
