These forms, in their turn, exert considerable back influence upon the structure of turbulent flow. To study this phenomenon, an extended program of experiments has been conducted, using devices that registered average velocities and their turbulent pulsations. The method of fluorescent tracers was used to study the dynamics of sediments in the flow. Experiments were conducted in the field conditions (at the Jordan River's
