The problem of local scour appears deceptively simple at the first sight, but continues to defy attempts of a rational solution. Due to the complex nature of the problem and a large number of variables involved a purely theoretical approach has been extremely difficult.

Local Scour Around Bridge Piers
Journal of the Hydraulics Division, 1969Local scour caused by the horseshoe vortex system which forms at the base of the piers is considered. Piers which induce a pressure field strong enough to cause the formulation of the horseshoe vortex system are termed blunt nosed; all others being classed as sharp-nosed piers.

Local Scour Downstream of Hydraulic Structures
Journal of Hydraulic Engineering, 1995An analysis of the problem of local scour downstream of hydraulic structures is presented here. This paper briefly discusses the functional design of the bed protection downstream of large hydraulic structures. Phases of the scour process and transport mechanism are treated in an introductory manner.

The investigation of flow intensity is crucial in understanding the ship propeller jet scouring process in ship manoeuvring areas, waterways path, and navigation channels. Although still water conditions are often used in studies, they do not accurately represent real‐life scenarios.

Overlooked Local Sediment Scour Mechanism
Transportation Research Record: Journal of the Transportation Research Board, 2004A 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

Local Scour at Piled Bridge Foundations
Journal of Hydraulic Engineering, 1998An experimental study of local scour around rectangular bridge piers founded on two circular cylindrical piles, where the piles are exposed as a result of scouring, is presented. The problem is the interaction of two widths (pier and piles) if the interface is set at different elevations with respect to the bed.

The present study investigates with laboratory experiments the scour downstream of a sill, followed by a rigid apron, in clear water scour conditions. Nine experiments were run, changing the discharge and the tailwater depth of the flow. The temporal evolution of the scour was recorded by a video camera and measured using image analysis techniques. The
