The authors discuss interaction between the river flow and the formation of the river bed as a
single dynamic self-regulating system. Changes in the physical-mechanical properties of river bed
sediments occurring under the influence of natural and anthropogenic factors, and the impact of
these changes produced on the processes of sedimentation and erosion of river channels are considered
in the article. Free and constrained precipitation of particles of different density, shape and
size are analyzed. A universal formula of the hydraulic resistance coefficient, applicable to particles
in the course of their sedimentation into the liquid, which takes account of both the front resistance
and the surface friction, is proposed. The authors also propose a formula that takes account of the
effect of concentration produced onto the rate of deposition. The experimental data reflecting the
impact of fine sediment on the viscosity and initial shear strength of the water and soil mixture are
considered. The results make it possible to improve the accuracy of calculations of channel processes
for the purpose of design of hydraulic structures, regulation of waterways and monitoring of
water bodies.
