De laatste tijd wordt er veel onderzoek gedaan aan cohesief sediment. Het speelt een belangrijke rol bij het ondieper worden van havens en waterwegen, en bij andere soortgelijke problemen. Om cohesief sedimenttransport te kunnen voorspellen zijn gegevens nodig over de verdelingen van de groottes en de bezinksnelheden. Er bestaan veel methoden om...

Recently a lot of research is being done on cohesive sediment. It plays a major role in the shoaling of harbours and waterways, and in some serious environmental problems. To predict cohesive sediment transport, information is needed about the distributions of size and settling velocities. Many methods exist to determine sizes of suspended...

Bed-levelling experiments are conducted in a straight laboratory channel. The experiments involve a significant fraction of suspended sediment transport. The purpose of the experiments is to provide data for modelling of the direction of sediment transport on a transverse sloping alluvial river bed, specifically in presence of suspended sediment...

A suspended sediment transport experiment in a straight flume with a mobile bed is reported. The bed topography is non-horizontal. The flow is steady. Due to an obstruction in the entrance a steady bed oscillation is generated. The bed topography is measured by means of manual bed soundings (by Delft Hydraulics). Suspended sediment...

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is reported. The flow is steady. The bed topography is measured by means of a profile indicator. Free and forced alternating bars are present. The steady part of the bed topography, which is forced by curvature, is characterized by a below...

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is described. The flow is steady. The median sediment diameter (160 micrometer) is larger than in the preceeding experiments, run no. 1 to 3 (90 micrometer). The bed topography is measured by means of a profile indicator. The bed topography is...

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is described. The flow is steady. The bed topography is measured by means of a profile indicator. The bed topography is characterized by a slowly damped oscillation of the transverse bed slope. Downstream of the bend entrance a pool and a...
