Abstract: A formula is derived for the prediction of the average velocity of a solitary coarse grain moving over a rigid flat channel bed. To verify the theoretical consideration, data collected in the present study and reported in ...

Abstract: The present study shows that the sediment pickup rate is better correlated with the densimetric Froude number than the Shields number. With laboratory data collected in open channel flows, an empirical formula for estimating ...

Abstract: This paper presents results obtained from a detailed analysis of the experimental data of three hydraulic jumps with low Froude numbers (1.5–1.9) in a narrow flume. With the increasing Froude number, the three generated ...

Abstract: An experimental study was conducted to better understand the settling velocity of porous spherical particles. Tests of the settlement of porous particles with porosity, ε, ranging from 0.53 to 0.86 in glycerol–water mixtures ...
