Abstract

The first part of this paper reviews the problem to correct instantaneous velocity measurements by applying a rotation. However, in fluvial geomorphology, the studied flow is often complex and streamlines may exhibit significant changes from one point of the measurement to the other, and applying a rotation complicates the situation more than it simplifies it. The second part examines the question of velocity data correction in complex flows using a field example of the turbulent boundary layer over a very rough gravel bed and a laboratory example taken from flow at river channel confluence
