Hydraulic action occurs when waves striking a cliff face compress air in cracks on the cliff face. This exerts pressure on … See more

The ability of waves to cause erosion of the cliff face depends on many factors.
The hardness (or inversely, the erodibility) of sea-facing rocks is controlled by the rock strength and the presence of fissures, fractures, … See more

There are three common forms of coastal erosion control methods. These three include: soft-erosion controls, hard-erosion controls, and relocation.
Hard-erosion control methods provide a more perm… See more

Storms can cause erosion hundreds of times faster than normal weather. Before-and-after comparisons can be made using data gathered by manual surveying, laser altimeter, or a GPS unit mounted on an ATV. … See more

A place where erosion of a cliffed coast has occurred is at Wamberal in the Central Coast region of New South Wales where houses built on top of the cliffs began to collapse into the sea. This is due to waves causing ero… See more
