COMPARISON OF TRANSPORT AND FRICTION OF MONOSIZED AND TWO-SPECIES SEDIMENT IN UPPER PLANE BED REGIME

Popis výsledku v původním jazyce

The paper focuses on a comparison of transport and friction characteristics of mono-sized and twospecies sediments at comparable flow conditions in the upper plane bed regime. Two fractions of artificial sediment (glass beads of the same density 2500 kg/m3 and different size 1.5 and 3 mm) were tested in sediment-transport experiments in a tilting flume. First, the sediments were tested separately and then mixed together. Measured flow quantities enable to evaluate bed load transport and bed friction from the tests. Furthermore, velocity profiles are mutually compared and relation among profile shapes, sediment transport, and bed friction is investigated. The velocity-distribution measurements include results from a grain transport layer above the erodible deposit. This enables to evaluate flow conditions in this layer and its role in bed-load transport and bed friction.
