Storm-generated dune armouring on a sand-gravel barrier

Artificial armouring of beaches and dunes by rockfill is a common response by man following wave-induced erosion during severe storms. The rarer occurrence, that of natural armouring of the seaward edge of a dune system perched as crest decoration on top of a transgressive sand-gravel barrier system, has been recorded at Carnsore Point, southeastern Ireland. Wave-lain stratified coarse sand to ...
