Abstract EN
Debris accumulation around bridge supports can constrict and redirect flow through the mutivents bridges resulting in significant bridge foundation scour.
The experimental study of this paper, aims to investigate the effect of different porosities of partial blockage at front of bridge pier on local scour depth formed around bridge supports.
The permeable blockage with different relative heights (H/Bp= 0.4, 0.8 and 1.2) was fixed on and above the mobile bed.
It was found that, for 15% porosity ratio of permeable blockage, the local scour depth at the left pier and right abutment was increased by 11.3% and 20% respectively compared to the no-blockage case.
In addition the permeable blockage that placed at the water surface produces more local scour depth at multi-vents bridge supports compared to its location on the mobile bed.
