OPEN CHANNEL TURBULENCE CHARACTERISTICS IN A ROUGHNESS LAYER FOR SMALL WATER DEPTH RELATIVE TO ROUGHNESS ELEMENTS HEIGHT
Journal of Japan Society of Civil Engineers Ser B1 (Hydraulic Engineering)
The flow structure around the bed, especially in gravel layer, is very important and needs to be clarified because the detailed topography of the bed exerts a significant influence on generation and dissipation of turbulent energy. A lot of channel hydraulics has considered smooth bed conditions but there are still many unsolved problems awaiting clarification for gravel bed rivers. This study investigates how the turbulence characteristics i.e. vertical distribution of longitudinal velocity,doi:10.2208/jscejhe.72.i_511 fatcat:utbovanbgzem3ixnxsj6laz5ym
