Evaluation of Scour Around Bridge Pile in Flood with Hec-Ras Software
Journal Title: Journal of River Engineering - Year 2014, Vol 2, Issue 6
Abstract
The maximum depth of scour around bridge foundations are the most important topics in hydraulic engineering. The effects of changes in flow rate on bridge scour around the base of the fifth Dezful Hsec-Ras were investigated with numerical models. For the first data field using a hydraulic model of the River Range Paul is in the software was created. Then use discharge in range 250 to 1850 cubic meters and investigate scour around pile of bridge. The result shows that increase was that the rates were low to moderate (329 cubic meters per second) of scouring around the base of the middle most value, but the rates and conditions of torrential amount of scour at the base right side highest value to allocated, as well as 1,630 cubic meters of flood conditions safely scour rate was lowest in the left bearing because the riverbed morphological and conditions of the secondary flow in bend is created.
