Herein there are theoretical dispositions on the conditions of the fluid flow and sand transportation within a wide range of rates. The results of some exploratory research on the sand transport in specially designed laboratory and production benches, including a platform with interchangeable modular polymer elements having an artificial rough surface, have been presented. The ranges of the experiment procedure have been established to create the turbulence zones, where the tray inner surfaces are of various texture in the form of obstacles of different height. The technique has been presented for carrying out experiments on large-size benches with modular pipe elements based on the use of photo and film equipment, as well as a set of devices for determining rates, filling and slopes. The results of hydraulic experiments on modeling the process of vortex formation in the flow in the trays with artificial roughness are presented. The ability of the flow to move sand dunes in the trays with an alternative texture of the inner surface has been studied, and the design data of the quantitative assessment of the transporting ability of the flow depending on various factors has been given.
