Evolution of Bed Shear Stress in Open-Channel Flow at Smooth-to-Rough and Rough-to-Smooth Transitions

Abstract The evolution of bed shear stress in open-channel flows due to a sudden change in bed roughness was investigated for rough-to-smooth (RTS) and smooth-to-rough (STR) transitions. The velocity field was measured in the longitudinal–vertical plane at high spatial resolution...
