In-Situ Visualization of Bedload in the English Channel
The objective of the TRAMAT campaign was to better understand the fate of fine particles in a predominantly coarse heterometric sediment. Sediment transport mechanisms were highlighted by in situ monitoring of hydraulic and particulate characteristics at and near the water-sediment interface using DYSPI (https://doi.org/10.4319/lom.2009.7.8). This monitoring was carried out during 3 periods of several hours on 2 different study sites: Vauville (-1.8788, 49.62762) on April 3-4 and April 8-9, and Saint-Brieux Bay (-2.5535, 48.74785) on April 5. ADCP current profiles were acquired simultaneously at the same sites.

The videos on sediment transport were acquired using the DYSPI (https://doi.org/10.4319/lom.2009.7.8). The time recorded in the files is UTC + 2 hours.
The current profiles were acquired using an RDI Sentinel V50 ADCP. The time recorded in the files is UTC + 1 hour for the Vauville site on April 3-4, and UTC for the Vauville site on 8-9 April and the Saint-Brieux Bay site on April 5. The ADCP was placed vertically on the DYSPI structure, facing towards the water surface, with the sensors positioned 1.8 meters above the seabed.
