MONITORING AEOLIAN ACTIVITY DURING A STORM EVENT USING A VIDEO SYSTEM

Research output: Chapter in Book/Report/Conference proceedingConference paper

Abstract

Aeolian sand transport was assessed from an Argus camera system located on a macro-tidal beach along the Belgian coast over a period of 4 days covering a storm surge. Over the study period, observed sand transport event occurred for 9.5% of the time when strong high oblique onshore wind (9.8m/s) combined with a water level below 3.75m TAW moved sand to the beach. Measured post-storm topographic profiles indicated an accretion on the total beach upper beach of 0.70m3/m, which was in agreement with the estimated potential sand supply of 0.91m3/m for the observed sand transport event and expected night transport events. Thus, there was a narrow temporal window in which sediment can be supplied to the beach before and after the storm surge. Also, the study highlights that the presence of berm with a relative height of 3m segments sediment transfer to the backshore.
