By order of Electricité de France (EDF) and Compagnie Nationale de Rhône (CNR) three discharge stations were realized in the Rivers Rhône and Saône. 300 kHz WorkHorse Horizontal ADCPs measure velocities that are converted to real-time discharges by our ViSea-H DAS software. The data are transferred to an EDF office through GSM communication. Moving boat discharge measurements were carried out to calibrate the H-ADCP discharge information.
