Abstract
    In the framework of the water management of waterbodies downstream of Liège, a monitoring campaign was set up with different parties during low water level event. A total of 40 Divers have been used in the field to map water levels for different waterbodies. The displacements of the parts of pressure sensors, exposed to the environment, are translated (using electronics) into pressure (Pa) and recalculated into water depth/height (m). Pressure sensors tend to drift due to irreversible deformation during the displacement of these measuring parts. Therefore the pressure gauges/sensors need to be calibrated before and after the deployment into the field. 40 divers from the involved parties have been collected and calibrated at Flanders Hydraulics Research. This factual report gives an overview of the calibration.
