An improved method is presented to determine the threshold boundary velocity required to entrain sediments under waves, using the non-dimensional group settling velocity of sediments ranging from very fine sand to granules ...

Although a combination of aggregate characteristics dictate particle settling, it is commonly assumed that large particles have higher terminal velocities. This simplifying assumption often leads to overprediction of large ...

Several researchers have studied turbulent structures, such as ejections, sweeps, and outwards and inwards interactions in flumes, where the streamwise velocity dominates over vertical and transversal velocities. However, ...

Many sediment entrainment equations for oscillatory waves are based on the linear (Airy) theory for deep water, but at the depth where such waves begin to transport sediments they commonly have trochoidal or cnoidal ...

VPA is an Excel spreadsheet to facilitate the analysis of current velocity profiles and its application to sediment transport studies in steady, uniform, open-channel flows. The program requires input values such as the ...
