Abstract: | A newly constructed coastal revetment at Colhuw Beach in the Glamorgan Heritage Coast, Wales, UK, was analysed using a recently
developed environmental risk assessment package (ERA). Conflict with Heritage Coast conservation objectives is apparent and
the act of building such a structure is questioned for a location where maintenance ofnatural beauty is an axiom of the coastal management philosophy. The likelyhood of revetment related environmental consequences of
significant magnitude was analysed using estimated probability values derived from Bavesian theory. The damaging impact of
the structure on the natural environment is out of all proportion to the level of storm protection afforded to the site. Analyses,
such as carried out via ERA, would have shown planners, engineers and environmentalists, the inadequacies of such an investment
and management strategy. The ERA approach can help to introduce greater clarity and consistency into decision making processes. |
