Hydraulic Performance of Xbloc+ Armor Unit

In recent years, the use of Xbloc units has increased exponentially. However, the placement of this unit is not always done as randomly as it should be and consequently, the stability of the armor is affected. In order to overcome this problem, Delta Marine Consultants is developing a new armor unit called Xbloc+ that has a regular placement. In...

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...

Breakwater roundheads under construction exposed to oblique waves

Construction of breakwaters is performed consecutively from core layer, filter layer, up to the armour layer. During construction, excessive damage is often encountered on core layers due to environmental conditions. The damage behaviour of core layers is similar to berm breakwater structures, where the initial profile is reshaped into a more...

Breakwaters under construction exposed to oblique waves

During the construction of breakwaters contractors often encounter undesired reshaping of exposed core material. This reshaping is comparable to the deformation process of berm breakwaters in which the outer profile reshapes into a more stable s-curve. In the case of oblique waves this deformation is enhanced by a longshore transport of stones...
