The study of bottom sediments in streams with mixed movement of clarified flow
Abstract
A technique has been developed for calculating the transport of bottom sediments when applying waves to the flow for conditions of clarified flow on the basis of laboratory research and analysis of modern ideas about the transporting ability of channel and wave flows in large earthen channels. As far as the authors of this article know, for the conditions of the clarified flow, there are no calculation methods, despite the fact that this issue is of great importance in analyzing the erosive ability of clarified flows when applying wind waves to it. At the end of the model, there was a special “pocket” for catching sediment coming from the tray, and a wave-producer at the beginning of the tray. In all experiments, at the first stage of the study, measurements were made under stationary conditions. For the clarified stream, as expected, the value of this coefficient turned out to be significantly less than for the conditions of a sediment-saturated stream: = 0.0002. At the second stage of the analysis, the specific consumption of bottom sediments was calculated when superimposed on the clarified wave of waves according to dependence (3) at = 0, 0002.
