The question of the study of hydraulic resistance to fluid movement in a turbulent regime has more than a century of history, but it continues to be relevant to this day. The extensive construction of numerous free-flow watercourses, as well as machine and diversion channels of hydropower facilities, requires scientifically based calculation methods. For the correct establishment of hydraulic calculation methods, a sufficiently deep study of the physical essence of the phenomena occurring in free-flow flows is necessary.
