STABILITY OF INTERLOCKING ARMOUR UNITS ON A BREAKWATER CREST

A New Symmetrical Unit for Breakwater Armour: First Tests

A new and symmetrical single layer armour unit, the crablock, has been designed in the UAE. One breakwater was reconstructed with crablock, but very limited testing had been performed. Just to become more acquainted with this new unit, precompetitive research at a university has been performed, which is the subject of this paper. Being a new armour unit, the placement was investigated first. Th...

Experimental research on the stability of the armour and secondary layer in a single layered tetrapod breakwater

Preface This thesis was submitted in conformity with the requirements for the degree of Master of Science (MSc) in Civil Engineering. The preparation and evaluation of the experiments were performed at Royal Boskalis Westminster nv. The experiments have been carried out at the Fluid Mechan-I want to thank him for guiding me through the total process of this research. During this graduation work...

The influence of the under layer on the stability of single layer armour units

Artificial Intelligence and Rubble-Mound Breakwater Stability

Breakwaters are coastal structures constructed to shelter a harbour basin from waves. There are two main types: rubble-mound breakwaters, consisting of various layers of stones or concrete pieces of different sizes (weights), making up a porous mound; and vertical breakwaters, impermeable and monolythic, habitually composed of concrete caissons. This article deals with rubble-mound breakwaters....

An Investigation on the Stability of Rubble Mound Breakwaters with Armour Layers of Antifer Cubes

This paper presents the results of hydraulic model tests on the stability of rubble mound breakwaters with armour layers of antifer cubes. The tests were performed using irregular waves. The effect of wave parameters and the structure slope on the stability of these artificial armour units has been investigated and the stability formulae have been derived. Finally a comparison between these for...
