Abstract
This paper studies scour features and velocity field using experimental and numerical models at
rectangular piers under influence of contraction upstream abutments. A bridge model of two vents
of 8cm width each is built to conduct experiments. Extra-piles are proposed upstream rectangular
abutments. Different relative extensions of piles are tested. In addition, a new abutment of a relative
width ranges within 0.0 to 1.25was proposed instead of piles. The flume’s dimensions are 40cm
width, 20 cm deepness and 400cm length. Some design rules are deduced to reduce scour upstream
rectangular piers. Cases of locating piles upstream abutments are simulated numerically using
SToRM solver in iRIC software. The numerical results indicate that, piles of a relative extension to
vent width = 4.812 produce the minimal flow velocity near rectangular piers.
