EFFECT OF GRAIN DENSITY ON PLANE BED FRICTION
Original language description
Sediment-transport experiments with different fractions of model sediment in a tilting flume are analyzed with the aim of evaluating the influence of the bed grain density on bed friction in the lower- and upper plane bed regimes. The water-flow based experiments covered 4 fractions of sediment from which 2 were glass beads and the other 2 plastic grains of different density. The experiments were carried out for a broad range of installed flow rates and flow depths producing a broad range of values of the bed Shields parameter and the delivered concentration of sediment. The paper discusses and quantifies how different densities of sediment grains affect the bed friction coefficient in flows with no delivered concentration of sediment (the lower planebed regime), and with high concentration of bed load (the upper plane bed regime). In the lower plane bed regime, the bed friction coefficient can be determined using the logarithmic law for the hydraulically rough boundary with the equiv
