Laboratory tests are described, in which the effect of impermeable groynes on an eroded beach was studied A beach was allowed to reach equilibrium for a particular wave climate and supply of littoral material The foreshore was then manually eroded, and the beach allowed to return to equilibrium with and without groynes It was found that the presence of groynes increased the rate of accretion but did not significantly build up the inshore beach beyond the stable levels Bed levels seaward of the groynes were increased.
