Abstract
The purpose of the work is to determine, in laboratory conditions, the magnitude and laws of distribution of bottom wave flow velocities, at which various stages of particle movement and riffle formation occur in the area of beach slopes of water bodies of the agro-industrial complex. The results of studies of velocities characterizing the regimes of sediment movement in a wave flow acting on loose slopes and bottom areas of the shallow zone of reservoirs and streams are presented. The influence of artificial flow turbulization on characteristic flow speeds, including wave speed on the parameters of bottom riffles, is considered. An analysis of the influence of artificial turbulization on the speed of sediment movement is given and recommendations are given for determining the non-erosive speed of the wave flow in its absence. A dependence is presented for determining the height of the riffles. It has been established that the velocities on the riffle crest increase by no more than 1.7 times compared to the speed on the flat bottom of the near-shore zone of a large water body.
