Local Scour Around Non-uniform Bridge Piers: Vortex Power Concept

Veerappadevaru, G. / Nagesh, M. A. / Devasharma, H.

The prediction of equilibrium scour depth is carried out by tweaking the power of the vortex that crops up in front of non-uniform piers. This modification is based on replacing the width of uniform pier with equivalent width for a non-uniform pier. The ratio of the projected area of the components of pier to the depth, Y_min constitutes equivalent width. Minimum scour depth occurs for type-I piers and to a depth Y_max at which maximum scour depth occurs for type-II piers. The vortex power concept is based on equivalent width and is tested using author’s experimental data relative to data available in literature. It is found that the prediction accuracy in both cases is substantially accurate.
