Overlooked Local Sediment Scour Mechanism

Transportation Research Record: Journal of the Transportation Research Board, 2004
A heretofore overlooked mechanism is described for the removal of sediment in the vicinity of a structure, such as a bridge pier, located in erodible sediment and subjected to water flow. The strength of this mechanism depends on, among other things, the ratio of structure width to sediment grain size, b/D50.

THE VORTEX SCOUR MECHANISM AT BRIDGE PIERS.

Proceedings of the Institution of Civil Engineers, 1981
The paper examines the problem of localised scour by analysing the cause of the scouring process itself. The scouring vortex which develops because of an upstream flow separation ahead of the pier, and which is considered to be the basic mechanism operating at bridge piers, is subjected to detailed experimental analysis.

A review of bridge scour: mechanism, estimation, monitoring and countermeasures

Natural Hazards, 2017
Scour of sediments around bridge foundations by the stream is the most significant contributing factor for bridge failures. The scour failures tend to occur without prior warning and have led to fatalities and economic loss every year. A significant amount of work has been conducted on bridge scour. Such efforts can be broadly classified into two major

Erosion mechanism of local scour around cushioned caisson on reinforced ground

Marine Georesources & Geotechnology, 2017
ABSTRACTThe scour behavior of cushioned caisson constructed on reinforced ground, which is used to support superstructure constructed in deep water in seismic zones, was investigated by experimental and numerical methods. Flume tests under nine different flow velocities between 18 and 48 cm/s were performed based on hydraulic similarity design ...
