Annotation	The experiments on dynamics of turbulent boundary layer on the plane rough wall without pressure gradient are to be presented. Sand roughness of the wall is considered. Measurements are carried out using Time-Resolved PIV technique in plains parallel and perpendicular to the wall. The results on rough wall are compared with the base case of boundary layer on smooth wall. Hairpin vortices and theirs packets have been detected. Topology and typical size of those structures substantially differ in the cases in question.
