Crablock Concrete Breakwater Armour Unit

Author: Phelp, D ; Tulsi, K ; Abdulla Al Masaood, HE ; Eissa, M Date: Feb 2012 During cyclone Gonu, a category 5 storm, which impacted the east coast of Oman in June 2007, a number of small craft harbours were severly damaged. Most of the breakwater structures were armoured with various sizes of rock protection. The Al ... Read more
GPU-based discrete element rigid body transport

Author: Govender, Nicolin ; Gledhill, Irvy MA ; Kok, S ; Wilke, N Date: Aug 2013 The protection of harbours and coastal infrastructure is of vital importance to South Africa. A major development in the design of packing strategies for breakwaters is numerical modelling, and the use of physics engines and DEM models. For ... Read more
Rehabilitation of Yzerfontein breakwater by Dolos armour units

Author: Letsie, Masupha M ; Tulsi, Kishan R ; Phelp, David T ; Johnson, Craig M Date: Jul 2015 The Yzerfontein breakwater was constructed in 1950 and has since been subjected to extensive deterioration. In order to extend the lifespan of the breakwater a maintenance program was to be carried out. Various options are described in the ... Read more
Simulating the rubble mound underlying armour units protecting a breakwater

Author: Cooper, Antony K ; de Villiers, R ; Greben, JM ; van der Bergh, F ; Gledhill, Irvy MA Date: Jan 2010 A variety of concrete armour units laid on top of rubble mounds are used to protect breakwaters and other harbour infrastructure. Coastal engineers build three-dimensional physical scale models to understand the dynamic processes caused by ... Read more
The use of physics engines in quantifying breakwater damage

Author: Gledhill, Irvy MA ; Greben, JM ; Cooper, Antony K ; De Villiers, R ; Grobler, Jan-Hendrik Date: 08 Jul 2013 The response of proposed breakwater packing strategies to incident waves is usually tested and evaluated in a model hall. There is currently also increasing interest in using numerical simulations to model both the packing of a breakwater, ... Read more
