Description :
The aim of this paper is to report on experiments designed to examine the role of dune geometry and wind velocity and direction on secondary lee-side airflow patterns during offshore flow conditions over a vegetated foredune along Magillan Strand, Northern Ireland. The implications for sediment transport and longer-term morphodynamic evolution are discussed. This study has found that dune shape is an important controlling factor in the type of airflow regime that prevails. The results offer an explanation for the presence of many beach-dune systems in lee-coast locations.
