Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 1990-08-01 Abstract 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 characterized by a slowly damped oscillation of the transverse bed slope. Downstream of the bend entrance a pool and a submerged point-bar are present, here the radial bed slope is maximal. Further downstream the transverse bed slope decreases and converges to a constant slope (constant in main flow direction), here the bed topography is axi-symmetrical. The topography resembles that of run no. 2 but has a more pronounced axi-symmetrical region. Suspended sediment concentrations are determined by the method of siphoning and by optical measurement. In the region of axi-symmetrical bed topography a dense measuring grid is employed.
