Annotation	The individual and joint effects of surface roughness and external flow turbulence on turbulent boundary layer were experimentally investigated in the closed circuit wind tunnel IT AS CR. Fundamental mean flow characteristics were measured in turbulent boundary layers either on a smooth plate or on the plate covered with the sandpaper (80- grits) under turbulent flow with the intensity of almost isotropic fluctuations from the natural value, of about 0.003 up to 0.05 and with the relevant length parameter from 2.2 mm up to 30.5 mm .
