Coastal Cliffs: Morphology and Management by Eric Bird

By Eric Bird

This booklet bargains an perception into the worldwide incidence, geomorphology, evolution, weathering and erosion of coastal cliffs and bluffs. Stabilization and maintenance of cliffs are taken care of intimately. Mitigation of cliff risks and protection of scenic beneficial properties and websites of clinical significance calls for potent coastal cliff administration which can in simple terms be according to thorough wisdom of the actual procedures at paintings.

Many rock falls occur on cliffs during unusually cold weather, especially when stresses develop as the result of freezing and thawing of groundwater contained in the rock formation. Rock falls on Chalk cliffs in southern England occur particularly during and after cold winters in response to freezing and thawing of groundwater in the Chalk; there is expansion and contraction of ice as it forms and melts.

Cliff-face rills and gulleys do not persist on cliffs that are being cut back rapidly by marine erosion. Cliffs cut in Lower Cretaceous (Wealden) clays and sands on the south-west coast of the Isle of Wight have been dissected by gulleys cut by runoff after heavy rain. A similar cliff of soft Tertiary sandstone at Black Rock Point, on the NE coast of Port Phillip Bay, Australia, has been dissected by vertical gulleys cut by occasional runoff (waterfalls poured over the cliff here during a heavy downpour in 1972), accompanied by the exudation of fine sediment by groundwater seepage.
