Sandfill-Retaining rubble mound structures: Evaluating the behaviour of sediments at the interface of a rubble mound with a reclamation, by means of physical modelling

Currently, sand retaining rubble mound structures are often constructed with geotextiles, lining the interface between the core material and the sandfill. These geotextiles are placed to make sure the sand from the sandfill is not flushed out through the core by incoming hydraulic forces from the surrounding water. It is proposed that...

Experimental research into the effect of freeboard on the stability of a crown wall on a rubble mound breakwater

A crown wall is a gravity based L- shaped concrete structure on top of a rubble mound breakwater. Functions of a crown wall are: reduction of wave overtopping, enable transport on the breakwater and placement of pipelines on top of the flat surface. Marine contractor Van Oord was awarded to extend a breakwater with a crown wall on top, located...
