Crest stability of XblocPlus armoured low crested breakwaters

XblocPlus is a single layer armour unit that is recently developed by BAM Infraconsult. It is the successor of the Xbloc. An important advantage of the XblocPlus is the relatively high construction speed compared to the Xbloc. The increased construction speed is caused by the possibility to place XblocPlus in a uniform pattern and the relatively...

Stability Optimisation of the top armour row of a breakwater with Xbloc^Plus units

The Xbloc^Plus (referred to as Xbloc+) is a new, uniformly placed single layer armour unit, developed by Delta Marine Consultants (BAM Infraconsult). Although a breakwater armour layer with Xbloc^Plus combines material saving and easy placement with increased stability, the transition between the armour layer and the crest is...

Stability analysis of XblocPlus crest element

In the past humans used to protect their shores mainly with rocks. In the past decades the shore protections did gently shift to concrete element protections. An example of an often applied concrete armour unit is the Xbloc. This element is quite strong and well investigated. BAM Infraconsult has developed a uniformly placed armor unit, the...

Rear-Slope Revetment Stability Approached by the Wave Overtopping Simulator: Experiments Regarding the Stability of Single-Layer Cube Revetment on Breakwater Crests and Rear Slopes

Contrary to a breakwater outer slope, rear-slope revetment does not have to withstand breaking waves. However, generally, an equal dimensioned revetment is used on both the inner- and outer slope. Although with low-crested breakwaters severe overtopping occurs, the application of similarly sized armour on both sides still results in an over...
