The vertical structure of turbulence in a channel with free boundaries is considered using experimental data. In particular, the vertical distribution of turbulent friction, the coefficient of turbulent viscosity, and the horizontal dimensions(scale) of the turbulence are considered. Experimental data obtained by recording the longitudinal and vertical components of the velocity by the thermohydrometer method are presented. The time and spatial Lagrange scales defined from the space-time correlations are given.
