Abstract

In this study, physical experiments are used to investigate the relationship between fluid velocities on the surface of two rubble-mounds and the shear stresses T and normal stresses a acting on the surface layer of rock armour. Results presented herein indicate that the peak magnitude of slopeparallel hydrodynamic forces on rubble-mound armour located below the still waterline can be reasonably well estimated using wave friction factors originally developed for rough turbulent oscillatory flow over impermeable horizontal beds. Stresses on rubble-mound armour are also compared to the prevailing surf similarity (Iribarren) parameter. The largest stresses are found to result from waves that form collapsing breakers.
