Using 3D terrestrial laser scanning technique to determine volume changes of a cobble beach

The use of cobbles as a dynamic revetment is a recent development in coastal protection. Cobbles are placed along the beach and they form a dynamic equilibrium with the waves, thus dissipating the energies from the wave and protecting the soft, native material from eroding. In order to optimize the design and increase the durability of this...

Cobble Sea Defence: Hydraulic Interface Stability of Sand underlying a Single Filter Layer

A cobble sea defence appears to be an easy constructible protection, with relatively low total costs of ownership. Flume tests show that sand under such single layered constructions is stable. However, it is not exactly known how the hydraulic loading of a breaking wave is reducing in the filter. Two datasets containing pressure measurements in...

Stability of rock on beaches

This report is a graduation thesis of a fourth-years student of the Delft University of Technology, Faculty of civil Engineering. The object of this thesis is to research the stability of stones on a mild slope under wave attack. A possible application is the protection of a pipeline crossing a beach exposed to hydrodynamic forces. For many...
