Physical Modelling of Dolos Breakwaters: The Coega Results and Historical Perspective
A large number of physical model tests have been conducted for the proposed Coega harbour in South Africa. The study entailed a thorough investigation into the stability of a dolos armoured breakwater subjected to breaking wave forces in water depths of up to 19 m. Dolos stability was optimised in terms of size, shape (waist-to-height ratio and fillet/chamfer sizes), packing density and armour slope angle. Trends used for steering the optimisation were based on extensive historic research tests together with model test results as they became available in the present study. Both two and three-dimensional tests were conducted in which a total of more than 7 000 dolos movements were recorded with a new PC based digital imagery method. To interpret these movements, a comparison with previous work was required, both with regard to dolos movements recorded in physical model studies and with respect to both physical model results and recorded prototype damage.
