Abstract
    In order to work out a disposal strategy along sandbars in the Western Scheldt, Flanders Hydraulics Researchconducted research combining field measurements and 2D high resolution numerical modelling. The Delft3Dsoftware was used for this. For the calibration of the numerical model, a lot of information and experience fromprevious modelling studies was available. In a first phase, the water levels in the model were calibrated byapplying a space varying Manning bed roughness coefficient: in this way the propagation of the tidal wavebetween the different measurement stations could be adapted in the model. In a second phase, the focus of thecalibration was on the flow velocities. The horizontal viscosity was used for this as the main parameter. For theintertidal area, the maps of ecotopes –were used to calibrate the flow velocity. A depth depending bed roughness as well as the critical velocity between high and low dynamic intertidal areas were used for the calibration. Combining the in situ measurements, the calibrated numerical models and the experience from 2 in situ disposal tests, the engineers of Flanders Hydraulics Research succeeded in working out an optimal disposal strategy.
