Abstract: Experiments were conducted to investigate the division of the total shear stress into a friction loss and a form loss component for flows with ripples on the bed. Four different sizes of glass beads were used as bed material, ...

Abstract: A general velocity distribution consisting of a logarithmic profile plus a wake function has been used to investigate the effect of suspended sediment on flow resistance. From the experimental evidence that the wake constant ...

Abstract: Using dimensional and theoretical analysis together with available experimental data, it has been shown how flow conditions and stream bed slope affect the beginning of sediment transport. The dimensional analysis shows ...
