Hydraulic action can also cause the breakdown of river banks since there are water bubbles which enter the banks and collapse them when they expand.

The soft composition of these sedimentary rocks also means that erosion by the sea through hydraulic action, abrasion and attrition is commonplace, and they are thus largely unsuitable for climbing.

The steel deck and the hydraulic action of the deck were designed by the Walloon engineering firm Greisch from Li�ge, Belgium, also an Information and communication technologies company of the Walloon Region.

Created by the erosion of a cliff through hydraulic action some time after 1750, the stack is no more than a few hundred years old, and may soon collapse into the sea.
