"Presented study deals with theoretical and experimental investigation of the steady uniform and transient flows with a free surface in channels with a circular cross section with smooth walls as well as with rough sediment deposits. The aim of the study is to define the relationship between the flow unsteadiness and selected flow/turbulence characteristics in circular tube running partially full. Furthermore, the influence of the sediment bed on spatial distribution on given characteristics is studied. The results show strong influence of the cross section geometry on the local values of friction velocity above the sediment bed. The temporal/spatial turbulence intensities and Reynolds stress distribution in the mid-vertical of the pipe were identified. Finally, the individual terms of the bottom shear stress were identified. The omittance of any flow property leads to clear misinterpretation of the calculated bottom shear stress." . . "3"^^ . "[9F62CA22FCCF]" .
