Bulbous Pier: Alternative to Bridge Pier Extensions

2015
Bridge deck splashing causes deterioration to the bridge structure and renders the bridge unsafe for motorist and pedestrians. The traditional countermeasure for bridge deck splashing is pier extension, the pier extension moves the pier wave away from the bridge deck, but retrofitting existing bridges with pier extensions is costly.

Stability of Riprap at Bridge Piers

Journal of Hydraulic Engineering, 1993
An experimental investigation was performed to determine the critical conditions for displacement of riprap placed on streambeds surrounding bridge piers. A functional relation between stability number, a dimensionless grouping of rock size and density to fluid velocity and density, and relative approach flow roughness, approach flow depth, riprap size,

Flow around Bridge Piers

Journal of Hydraulic Engineering, 1998
This paper presents the results of a laboratory study on flow past cylindrical piers placed on smooth, rough, and mobile beds. Experimental results are presented on the flow in the plane of symmetry, including the frontal downflow and the effects of bed roughness and the scour hole on it.

Scour at bridge piers and abutments

2016
In this thesis several of the formulae that have been put forward to predict scour are examined and some of their limitations pointed out in an attempt to clarify some of the research work that has been done on scour. The formulae are applied to two known bridge failures and their accuracy in those particular situations examined.
