Sediments suspended in turbulent flows of water over plane beds are known to influence the structure of the flows by which they are carried. Past attempts to model this effect have been based almost exclusively on a theoretical framework in which the dense solid particles stratify the flow and have an influence analogous to that of a downward heat flux in the stably stratified atmospheric surface layer. The authors compare results from a model based on this theoretical framework with laboratory measurements of ensemble-averaged velocity and ensemble-averaged particle concentration, obtained by previous investigators, in order to test the applicability of the theoretical approach to dilute suspensions of sand in turbulent flows of water.
