Hydraulic systems are based on the principles of fluid dynamics; this important branch of science deals with the movement of fluids. An understanding of the key principles of fluid dynamics is, therefore, essential for anyone who wishes to build or maintain hydraulic systems. One of the first concepts that must be understood is how physicists ...

Loose materials may be picked up directly by currents and wave action and moved offshore or along the coast. Further, solid rock may be directly eroded by the hydraulic action of breaking waves. When a wave breaks against a cliff, the impact of the water is capable of exerting pressures of greater than 250 kg/m 2 (6000 lb/ft 2). Water is …

The change in water level caused by tides, however, allows waves to attack a greater range of elevations on the coast. Wave impact directly exerts great pressure and can be a highly effective agent of erosion. The pressures produced by breaking waves have been measured by dynamometers, with reported values as high as 250 kg/m 2 (6,000 lb/ft 2).

Erosional processes along coastlines include: (1) the direct effects of hydraulic action, wedging, and cavitation by waves; (2) abrasion (corrasion), using sand, gravel, and larger rock fragments as tools; (3) attrition of the rock particles themselves during this abrasive action; (4) salt weathering or fretting; (5) erosion by organisms …

This would be consistent with hydraulic machinery being within the domain of hydraulic, not coastal, engineering. However the impact of these devices which will be deployed in large-scale arrays or a barrage on coastal flows is certainly within the domain of coastal hydrodynamics.

Weathering also plays a role in the rate of erosion by creating weaknesses in rocks that are exploited by the processes of erosion. Freeze-thaw weathering, for example, creates cracks in rocks, increasing the rock's susceptibility to hydraulic action. As always, humans have an impact on coastal erosion.
