WebThe active cliffs present a major sediment source for the sediment-starved Baltic Sea coast of S-H. Due to ongoing cliff erosion, about 39,000–161,000 m 3 yr −1 of sediments (0.063–64 mm) are annually supplied to the nearshore system. This is essential for the coastal transport and the stabilization of adjacent sandy shorelines. WebIf marine erosion at the base of cliff is much faster than the sub-aerial weathering of cliff face and crest, overhanging cliff with steep vertical face is formed. On the other hand, if the sub-aerial processes dominate over marine processes the verticality of cliff disappears and the cliff loses its true cliff character.
