2009/10/29
The paper presents a simple mathematical model for sediment transport in
straight alluvial channels. The model, which is based on physical ideas related to
those introduced by Bagnold (1954), was or...

In an earlier investigation of the behaviour of tracer particles for determination
of bed load transport in an alluvial stream (Thomsen 1080), specific
records were taken of the particle velocities ...

River flows with high volume concentrations (20-50 %) of silty sediments generally
imply that the mixture has non-Newtonian properties. In this study, the
rheological behaviour of mixtures with soli...
