Controlling Mechanism of Local Scouring

Journal of Hydraulic Engineering, 1990
Experimental study of clear water scouring around a circular cylinder shows that the scour mechanism is coupled to the three-dimensional separation of the upstream boundary layer and the periodic vortex shedding in the wake of the cylinder. The first scour appears in the wake of the cylinder.

Ice Scours as Trapping Mechanism for Shallow Gas

Proceedings, 2013
Shallow gas is commonly found on the Norwegian Continental Shelf and is a potential geohazard for drilling operations. Examples of shallow gas in Upper Pliocene sediments, in the Central North Sea is presented, and a model for how buried ice scours can act as a trapping mechanism for shallow gas is proposed.

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/D 50

Mechanics of Pipeline Scour Propagation in the Spanwise Direction

Journal of Waterway, Port, Coastal, and Ocean Engineering, 2015
AbstractThis paper presents the results of an experimental study on the mechanics of pipeline scour propagation in the spanwise direction. The experiments were conducted with uniform sediment under a unidirectional steady current in clear-water conditions.

Mechanism of scour around two piers

Pollack Periodica
AbstractScour around the bridge piers is the main cause of bridge failure below any bridge pier placed within the waterways. It is more than hundred years back a number of researchers described the vortex shedding phenomenon and the resulting Aeolian tones from a circular cylinder.

Tsunami Scour Mechanisms Around a Cylinder

2001
The scouring mechanism due to tsunami run-up around a vertical cylinder was investigated experimentally using a large-scale tsunami experimental facility. A variety of solitary waves were generated and allowed to run up onto a uniformly sloping sandy beach.

Mechanisms in anaerobic bioflocculation of wool scouring effluent

Water Research, 1994
Abstract The emulsified grease in wool scouring effluent (WSE) was demonstrably removed by bioflocculation under anaerobic conditions. The addition of anaerobic bacteria from biogas digestion to WSE resulted in grease reduction of 60–80% from the supernatant.

Mechanism of aerobic biological destabilisation of wool scour effluent emulsions

Water Research, 2005
Wool scouring effluent is a highly polluted industrial wastewater in which the main pollutant, wool wax, is held in a stable oil-in-water emulsion by non-ionic detergent. The use of microbial action to cause emulsion destabilisation has been proposed as a new treatment strategy for this effluent stream. This strategy aims at improving aerobic treatment
