Abstract

The paper describes the application of a novel method of protecting parts of the sand dunes at Pendine, S.W. Wales. These dunes are subject to erosion under conditions when high tides are combined with south-westerly gales. A series of random rock-fill mounds were sited 20 feet away from the toe of the dunes in certain areas where structures erected on the dune crest were liable to damage through erosion at the toe of the dunes. The object of the mounds is to trap wind-borne sand in the area enclosed between the mounds and the dunes, and also to check wind-driven waves before they can reach the dune face. Over seven years the mounds and sand traps have operated in accordance with their design concept. Not only have the traps filled with sand but further sand accretion has occurred on the protected dunes, resulting in a flatter slope and a strong growth of self-sown pioneer vegetation on the protected face and on the sand trap surface.
