Modelling the seasonal dynamics of SPM with a simple algorithm for the buffering of fines in a sandy seabed

This paper discusses the application of a simple algorithm for the buffering of fines in a sandy seabed. A second layer is introduced in which fines may be stored during calm weather and from which fines may be resuspended during storms. The algorithm is applied first in a one-dimensional vertical (1DV) point model at a location in the North Sea...

Description of the turbulence measurements conducted in the tidal channel "Groote Gat" (Ems/Dollard) in 1995 and 1996

In 1993 an interdisciplinary research programme on the behaviour of mud in tidal waters was initiated by the Board of NWO-BOA. The programme aims at obtaining more detailed insight in the dominant processes that govern the transport behaviour of mud. These processes have strong time variability and therefore the general approach is to obtain...

Bed-levelling experiments with suspended load

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-load experiment in a straight flume at Delft Hydraulics

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...

Suspended-load experiments in a curved flume, run no. 6

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...

Suspended-load experiments in a curved flume, run no. 5

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...

Suspended-load experiments in a curved flume, run no. 3

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...

Suspended-load experiments in a curved flume, run no. 2

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is described. The flow is steady. The aim the of experiment is to obtain data on the axi-symmetrical region. The bed topography is measured by means of a profile indicator. Downstream of the bend entrance a pool and a submerged point-bar are...

Suspended-load experiments in a curved flume, run no. 1

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is described. The flow is stationary. The main purpose of the experiment is to provide data to calibrate and test morphological models for river bend flow with suspended sediment. The bed topography is measured by means of an profile indicator...
