Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 1988-12-01 Abstract 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. Suspended sediment concentrations are determined the method of siphoning and by optical measurement. The experiment displays over- and undershoot effects due to the abrupt change of flume curvature at bend entrance. The stationary bed topography is characterized by a slowly damped oscillation of the radial bed slope. Within the 180 degree bend two maxima of the radial bed slope are observed, these correspond to one period of oscillation. The radial bed slope, throughout the whole bend, is not-constant in streamwise direction. Consequently the experiment does not include the axisymmetric solution; i.e. a region in which the variables are in equilibrium with the curvature of the flume. Concentration verticals, throughout the whole bend are reported. The depth-averaged concentration field displays a phase lag with the bed topography.
