Lateral dispersion on solid particles in water flow
Chára, Zdeněk ; Vlasák, Pavel
The paper presents the results of investigation of solid particle motion over rough bed in an open channel flow. The turbulence characteristics of water flow were performed by means of LDA, the particle motion was analysed by a video camera. It was found that the mean deviation angle by which the particles are moving to side walls is about 2.4ř.

Numerical model of saltation in open channel with rough bed
Kharlamova, Irina ; Vlasák, Pavel
The present contribution deals with a numerical modelling of a saltation of solid spherical particle in turbulent flow along rough bed in the open channel. The goal of the research is to obtain the dependences of average characteristics of particle saltation motion (as length and height of one particle jump) on flow parameters (which can be characterized e.g. by shear velocity and water depth) and bed roughness. The suggested dependences and calculated results are compared with analogical relationships introduced by other authors in literature.
