Motion of spheres falling through fluids is a classic problem in fluid mechanics. The problem is solved for steady motion and other special cases such as for small and large Reynolds numbers, but not yet for transitional flow motion because of t[...]

The current pier scour design in the USA is mainly based on the CSU equation, yet a recent incisive evaluation indicates a need to change it because substantial advances were made in the last two decades for understanding the pier scour processe[...]

The current design of bridge foundations based on equilibrium scour depths is much larger than the real maximum scour depth since peak flood periods are often too short to reach equilibrium conditions. Based on a tested hypothesis on the time ra[...]

Pradeep C. Fernando, Auteur ; Junke Guo, Auteur ; Pengzhi Lin, Auteur |This research presents an experimental study in a spatial wave basin for nonlinear interaction of regular waves with a perpendicular shear current over a movable bed. Detailed measurements were collected for current velocity profiles under diffe[...]

Pradeep C. Fernando, Auteur ; Pengzhi Lin, Auteur ; Junke Guo, Auteur |A theoretical model is presented to describe the current velocity within and outside a wave–current boundary layer and to quantify the associated bed shear stresses for wave–current interaction at an arbitrary angle. The model assumes that the w[...]
