Abstract:The sand bed in the Waal river is characterised by river dunes. The hypothesis is that river dunes become normative for the navigation depth during low water if sufficient water depth is created at five local spots with the least water depth (in Dutch: Minst Gepeilde Dieptes). These local spots do not erode uniformly with the rest of the river bed due to the presence of the fixed layers. Water movement induced by navigation affects the geometry and celerity of the river dunes. The aim of this research is, therefore, to quantify this potential effect of navigation on the geometry and celerity of the river dunes to improve river bed management.
