In order to quantify the siltation in the river Ems, a large measuring campaign has been organized by The Bundesanstalt für Wasserbau (BAW). In  June and July 2015, eight 13-hour cross-sectional measurements were performed at several locations on the river, for the derivation of sediment concentrations and fluxes.  Aqua Vision mobilized three survey vessels at the Ems river and performed simultaneous measurements for the period of one week. After acquisition of ADCP, OBS, CTD, SES and water sample information the data were processed by Aqua Vision using their ViSea Plume Detection Toolbox and ViSea Data Presentation Software.
