Resistance of submerged groynes

Groynes are commonly used in the major rivers in the Netherlands. They confine the flow of the river to a main channel but also act as resistance element once submerged and in that way influence the stage discharge relationship of the river. Several formulas exist describing groynes as a drag resistance. Another possible way of determining their...

Quantification of maintenance dredging uncertainty on the Waal

Large-scale river projects are executed on the Dutch rivers to meet increased flood conveyance standards. Because the projects bring variation to the standardised river profile, they are expected to induce increased river dynamics. The consequences are higher dredging costs and more disruption to inland navigation. All river intervention plans...
