Numerical modelling of flow depths and velocities at the crest of a rubble mound breakwater using OpenFOAM®

Breakwaters are built in coastal zones to alter sediment transport, or protect threatened habitats and port facilities. The rising sea level is causing more water to overtop these structures. Increasing amounts of overtopping discharge can compromise the security of people, or equipment standing on the crest of breakwaters. The overtopping flow...

Stability of a Crown Wall on a Breakwater: A refinement of existing design formulae

This thesis investigates the stability of a crown wall situated above SWL (Still Water Level) on top of a rubble mound breakwater. Crown walls are concrete super structures implemented commonly to provide a flat surface for pipelines and to make the breakwater accessible for vehicles. The vertical distance between SWL and the bottom of the crown...

Wave overtopping at rubble mound breakwaters with a non-reshaping berm

This thesis focuses on wave overtopping at rubble mound breakwaters with a non-reshaping berm. The research was aimed at gaining insight into the influence of a permeable berm on the overtopping behaviour. Moreover it was desired to validate existing prediction methods for the spatial distribution of overtopping for breakwaters with a non...

Scour below the toe of breakwaters: Investigation of scour formation through a geometrically open filter configuration located at the toe of a rubble mound breakwater lying upon sand

Scour formation at the toe of a rubble mound breakwater can lead to abrupt failure. Nowadays, counteraction of scour via geometrically closed filter rules, geotextiles or combinations is the common practice. Alternatively, in specific cases the use of geometrically open filters can save significant amount of time and decrease constructional...
