The area of intertidal areas in the Netherlands has tremendously decreased over the last decades. For management of the remaining area of inter tidal areas, knowledge of how these basins catch sediment is indispensable. One of the processes which is expected to be responsible for catching fine sediment en intertidal areas is part of this study: the interaction between turbulence and sediment induced buoyancy effects, which might lead to sediment-induced density currents and the possible collapse of the turbulence field and concentration profile when the saturation concentration is exceeded. In this project this feed-back mechanism is investigated by means of a data analysis. The data analysis concerned velocity, turbidity and water level measurements at the Paulina intertidal area in the WesterScheldt. The velocity and turbidity data were collected at two levels. This allows one to gain information on vertical gradients. The generation of density currents was expected to be visible in the vertical concentrati
