Sediment management is necessary to keep the Waal navigable. Sediment management in the Waal is carried out by both dredging and plowing of the river bed. By analysing historic data available at Rijkswaterstaat, the relation between the hydrograph and the amount of required dredging and plowing is investigated. Also the influence of the hydrograph on dredging and plowing locations are investigated. The locations of dredging and plowing are placed into context of the river geometry. The different results for dredging and plowing are compared to each other and substantiated.
