Experimental study on local scour depth around pile groups

Energy Reports, 2022
An accurate prediction of local scour depth at piles is essential for bridge safety. In order to obtain the prediction formula of local scour around pile groups, a series of local scour experiments of pile groups were carried out.

The effect of hydrostatic water level on the local scour downstream of plunging aerated jets. [PDF]

Sci Rep
This paper reports an experimental study on the effect of hydrostatic water level on local scour downstream of plunge aerated jets. To examine the shape of the scour for non-cohesive bed material, different flow and air rates, and different aeration ...

Riprap mitigation of downstream scour at grade-control structures considering tailwater depth and layer thickness. [PDF]

Sci Rep
Downstream scour at grade-control structures (GCSs) poses a serious threat to structural stability and riverbed integrity. Among various countermeasures, riprap has long been recognized as a cost-effective and readily available solution for scour ...
