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,

Numerical simulation of the turbulent flow around a complex bridge pier on the scoured bed

European journal of mechanics. B, Fluids, 2019
The present study aims to contribute to the numerical simulation of the flow behavior around a complex bridge pier with the scoured bed. For this purpose, a custom Large Eddy Simulation model was developed in which the pier and bed geometries are modeled

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.
