- •
Interannual variabilities of sorted bedforms are determined using hydroacoustics.
- •
The flow-transverse structures are maintained by tidal currents.
- •
They were stable (with oscillations) for four years.
- •
A major mobilization of fine sand seems to occur only during storms.
- •
Storm directions and intensities are manifested in superimposed ripples.
