Abstract
The article considers various approaches to assessing the physical essence of the von Karman constant characterizing the vertical distribution of the flow velocity. On the one hand, the von Karman constant is a proportionality coefficient between the length of the mixing length and the depth; on the other hand, it characterizes the tilt angle of the vertical velocity profile. It is considered that this parameter is universal, that means it is constant as long as the averaged velocity distribution is constant. However, depending on estimation way of this constant, its values under the same conditions may differ to 2 orders. Two methods for estimating the von Karman constant are considered. In the first case, determination of the von Karman constant is on the grounds of direct measurements of the maximum and average flow velocities, depth and slope of the water surface in a particular area. Propagation of the obtained value to other obj...
