Abstract

Control of shingle beaches for coast protection and/or sea defence may require use of rock groynes or shore-detached breakwaters. Experience from coast protection schemes on shingle beaches along the south coast of England however suggests that some control structures, including rock groynes and rubble revetments, have suffered greater damage than had been expected. This damage seems to have been most closely associated with steeper beach slopes. This report summarises information from recent research studies on the stability/damage behaviour of rock armour on 4 general beach control structures: a) simple 1:2 rubble sea wall slope; b) rock bastion or roundhead groyne; c) inclined crest rock groyne; d) L-shaped rubble groyne adapted from b) above. The report is aimed at coastal engineers who require information on the analysis/design of rock armoured beach control structures. It summarises data from a number of previous studies by HR Wallingford and co-workers, and includes results from recent wave basin tests.
