Description :
In this study, an intertidal bar and trough system on the beach of Noordwijk was monitored over a 15-month period in order to examine the daily to seasonal sequential cross-shore behaviour and to establish which conditions force or interrupt this cyclic bar behaviour. The beach morphology (bars and troughs) was classified from low-tide ARGUS video images based on surface composition. From the classified images, time series of the landward boundary of the bar and the trough were extracted. The time series of the boundary positions exhibited very little longer (seasonal) scale variability, but somewhat larger smaller (daily) scale variability.
