Abstract
Interaction of turbulent flows with the river bed being eroded constitutes a
complicated process of formation, under the influence of turbulent velocity
fluctuations, of sand waves and ripples on the sandy bottom. 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
