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...

Abstract Pile breakwater is an artificial coastal structure consisting of closely spaced piles. Its benefits are similar to other structures by attenuating the energy incoming wave. In this paper, wave attenuation caused pile investigated using a numerical model, namely SWASH model. The model allows for simulating non-hydrostatic phenomena in waters as driven waves. setup conducted rectangular ...
