Abstract: A theoretical analysis of the liquid free-surface formation and the development of fine silt concentration caused by the influence of a prevailing combined vortex is presented. Similarity relationships for both parameters have been found to exist. Burgers' vortex has been used to derive approximate formulae for the free-surface and the concentration profiles. Finally, using the present analysis, values for the diffusion coefficient have been calculated.
