Wind and Sand Transport Across a Vegetated Foredune Slope

Vegetated foredunes are widespread aeolian landforms along wave-dominated sandy coasts. In contrast to previous advances in dune erosion during storm surges, there is a little empirical data and understanding of processes foredune recovery growth. Based on comprehensive set (airflow, sand transport, topography change, vegetation cover) collected across steep (1:2.5, 21.8°), high (20 m) windy 5-week period at Egmond aan Zee, the Netherlands, we demonstrate agreement with studies that shore-perpendicular winds accelerate by factor 3 from foot crest but result low mass fluxes maximum dunefoot, favoring local deposition. contrast, oblique alongshore up accelerated less (or even decelerate) important bringing dunefoot slope, where it deposited when cover exceeds about 50% density measured crest. Moreover, our suggest sediment flux limited fetch-induced availability, whereas transport capacity, which depends wind velocity distance traveled over vegetation. Our study thus highlights importance direction growth recovery.
