Stability Tests and Damage on Breakwaters Armoured with Tetrapods
The objective of this paper is to evaluate damage in breakwaters armoured with tetrapods using physical modelling data. The hydraulic laboratory tests reproduced the complex geometry of a rubble mound breakwater armoured with tetrapod concrete blocks and subjected to breaking wave action. The test programme included both flume (2-dimentional; 2D) tests and wave basin (3-dimentional; 3D) tests using several combinations of input parameters, such as wave heights, wave periods, and wave directions, water level elevations, and tetrapod sizes. During physical model tests, the hydraulic stability of the tetrapod-armoured breakwater was evaluated, and the damage was measured for every design storm segment using the ‘flickering’ technique. The results obtained from the laboratory tests are in general similar to those predicted using published literature regarding the stability coefficient (KD) of Hudson’s formula.
