COASTAL PROCESSES
,▶ 4 main ways waves erode coastline; Hydraulic actio
▶ Big waves have a lot of energy and water is a dense
material – one m³ of water weighs one ton.
▶ Waves perform a number of complex and interacti
processes of erosion.
▶ Hydraulic action is an important process as waves
break onto cliffs
▶ As waves breaks against cliff face, any air trapped in
cracks, joints and bedding planes is momentarily
placed under very great pressure.
MARINE EROSION
, ▶ As waves retreat, pressure is released with explosive force
causing stresses which weaken the rock’s coherence,
assisting erosion comparable to cavitation in rivers.
▶ Hydraulic action is particularly obvious in well-bedded an
well-jointed rocks such as limestones, sandstones, granite
chalk but as well as in poorly consolidated rocks such as
clays and glacial deposits.
▶ Hydraulic action is notable during times of storm wave
activity. One such example is the average pressure of
Atlantic storm waves which is 11 000kg/m².
▶ This process is known as wave pounding.
