Abstract: It is experimentally demonstrated that fitting the log law to the mean velocity profile in turbulent open-channel flow to determine the friction velocity, roughness length, and zero-plane displacement, can lead to relatively ...

Abstract: A new criterion for the experimental characterization of the threshold of motion of sediment as bed load is introduced and this criterion is implemented in an experimental investigation of the role of sediment packing ...

Abstract: An advanced image analysis system, called Khoros, was used to investigate the bed load movement of sediment particles in a laboratory flume. Incipient flow conditions prevailed throughout the experiments. Painted glass ...
