CoastCare Techincal Information

The hydrodynamic stabilisation principle is based on reducing the time interval required for the pressure gradients created by the effects of retreating seawater after permeating the swash zone.

This allows the sand to settle and stabilise earlier so that the sediment transported away from beach by the retreating seawater in the swash zone is reduced, while at the same time increasing the ability of the beach to trap a part of the sediment washed in by wave action. This basic property of the system promotes sedimentation of materials along the coastal profile where it is implemented.

When the water level is low on the coast during the period from low tide to high tide, the water circulation in the swash zone increases, which again increases the depositing of materials on the foreshore, thereby building up the beach from the sediments transported along the coast.

Over time the new materials in the coastal profile are increasingly coarse, due to the higher speed of the underlying water in the coast profile.
