Description :
This study aims to identify the significance of foredune characteristics and beach width on differences in local wind characteristics and aeolian transport on a raked site and a nearby unraked site that evolved by natural processes. This was conducted on the developed coast of Avalon, New Jersey, USA. Wind speed were monitored using anemometers placed at 1 m elevation and sand transport was monitored using vertical traps during oblique onshore, alongshore and offshore winds occurring in March and April 2009. Aeolian transport rates were greater on the narrower but dryer backshore of the unraked site. Vegetation growth may be necessary to trap sand within zones of buried wrack in order to allow new incipient foredunes to evolve.
