Experimental data of sediment bed behaviour in a current@en

This data set has been collected in annular flume experiments with bimodal sand mixtures at the University of Waikato, New Zealand. Medium sand (D50,c = 400 µm) was mixed with 40 % fine material of different diameters (D50,f = 53; 111; 193 µm) and subjected to increasing flow velocities (U = 1.3-22.2 cm/s). The near-bed hydrodynamics, the bed level and the suspended sediment concentration were investigated. In the affiliated publication (DOI: 10.1002/esp.4559) selected results are compared with results from similar tests with glass beads. […]
