STABILITY OF ROCK ON BEACHES

Abstract


Stability relations for rock on a mild slope are derived and compared with experimental results. It appears that for non-breaking waves the stability on a mild slope can be described with existing relations for stability on a horizontal bottom in oscillatory flow. For breaking waves, no existing relation can be used and a provisional empirical design rule was established. The results can be applied in designing outfall protections.
