TENEVIA RiverBoard® is a patented system of measuring and helping to monitor waterways based on image analysis and processing. It uses the images supplied by a surface-based image acquiring device (IP camera and infrared projector) installed very close to a waterway or canal to measure the water’s height and surface flow velocity and calculate the discharge.

The non-intrusive nature (not submerged) of this solution means that it continues to function during extreme events such as flooding. Designed as a hydrometric information service, TENEVIA RiverBoard® is a "4 in 1" data and measurement display system (height, velocity, discharge and visual control using video) making it possible to:
- create and update a rating curve using a number of discharge estimates calculated by the software using the images;
- obtain two discharge calculations: the discharge estimated by the current rating curve (Q) systematically, as well as the discharge estimated using the surface velocity measured (Qcalc) on an ad hoc basis;
- detect changes in hydraulic behaviour (i.e. rating curve shift).
