Abstract

This paper presents the results of a research study to quantify the stability of rock armoured groynes on steep shingle beaches. The research was needed to identify why significant numbers of rock revetments and groynes have suffered greater damage than would be predicted by conventional design methods. The paper describes the design and execution of tests in a large wave basin, at notional scales of 1:10-20, on four types of typical beach control structures. The test structures were constructed on a model shingle beach of slope 1:7, and were subjected to random waves of steepnesses sm=0.02 or 0.04. The tests confirmed that armour damage may be substantially greater than predicted by existing methods, even on simple slopes under normal wave attack. The results of the damage analysis have been used to suggest modified coefficients to van der Meer's plunging wave formulae.
