Abstract: In this study, six different types of flow-altering countermeasures against pier scour were evaluated experimentally. The selected countermeasures were submerged vanes, bed sill, transverse sacrificial piles, collar, ...

Abstract: Results are presented and discussed from two laboratory experimental campaigns specifically designed to investigate the behavior of a slot as countermeasure against local scouring at a smooth circular bridge pier, close ...

Abstract: An experimental campaign of 21 long-duration tests on scouring at complex piers of different configurations was performed to investigate the effect of pile cap thickness on the temporal evolution of the maximum scour depth ...

Abstract: Results are presented from laboratory experiments to investigate the effectiveness of bed sills as countermeasures against local scouring at a smooth circular bridge pier, for flow conditions near the threshold of uniform ...

Abstract: The conditional double-averaged streamwise velocity, spatially averaged (SA) turbulence and dispersive quantities in flows over a water-worked gravel bed (WGB), and a screeded gravel bed (SGB) were studied. The effects of ...
