- Summary
- Aeolian sedimentation across an Ammophila arenaria-dominated foredune was assessed for eight months using sand traps. This research aimed to ascertain if such foredunes act as a barrier to transport between beaches and hinterland dune systems. At Mason Bay, sand was transported across the foredune at rates of up to 10 kg.hour-1 per 100 m length of coast at wind velocities of 31 m.s-1 . Results were compared with computational fluid dynamics modelled airflows and foredune volume changes. Saltation was important for up to 17 m past the stoss face. Rates of transport were well short of rates of volume gain. Approximately 2% or less of stoss face suspended sediment transport reached the hinterland. The foredune is primarily a sand sink.
