PREDICTION OF MOVEMENT OF A LARGE BOULDER IN THE CHANNEL OF THE MOUNTAIN STREAM
Journal Title: Engineering and Technology Journal - Year 2022, Vol 7, Issue 4
Abstract
As it is known, according to the type of formation, density, and fractional composition, debris flow is divided into two dynamic categories – cohesive (turbulent) and adhesive (hyper-concentrated, structural). Cohesive debris flows, the contents of which are represented in water as a soil suspension, obey the general laws of hydromechanics. Adhesive debris flow is not characterized by turbulent interchange, which is caused by saturation of the flow with fine fractions and adhesive water. Since, in certain sections of the transit zone of the flow, there are such changes in morphometric characteristics that are often not subject to assessment; the analytical solution of hydraulic problems of debris flows does not lose its relevance and is the object of research of many researchers. According to the above mentioned the article deals with the problem of the rectilinear motion of a boulder in the streambed with a positive bottom slope under the influence of water flow and gravity of a boulder. We obtained the equation for calculation of the average velocity of the water flow in order to transport a large boulder, which is partially submerged in the stream.
