Scour Development at Elliptical Guide Banks during Multiple Floods

The scour development at bridge abutments and elliptical guide banks during multiple floods is studied. At the upstream head of the elliptical guide bank, a streamline concentration, a local increase in velocity, vortex structures, and the development of

Temporal variation of local scour at bridge piers with complex geometries

, 2012
Scour at uniform cylindrical piers founded in cohesionless sediments has received much attention over the last decades and there are extensive laboratory data for these conditions in literature.

Scour, Local and Critical Velocities at the Abutments on Plain Rivers

Local flow modification near engineering structures such as – local velocity, flow separation, circulation, vortex structures, and increased turbulence, leads to local scour near foundations.

Propagation modes of 3D scour below a submarine pipeline in oblique steady currents and waves

, 2016
This paper presents experimental results on 3D scour propagation along a pipeline under oblique-incidence currents and waves. Different modes of 3D scour propagation were discovered after the local scour was initiated below the pipeline.
