Abstract
An experimental investigation of scour depth variation is presented herein with an objective to examine efficacy of application of collars to a bevel-nosed rectangular pier in reducing the scour depth. Bevel-nosed rectangular pier aligned with the flow direction at low angles of attack with flow was tested without collar, with one collar and two collars under steady-state clear-water scour uniform flow condition. 76.7% and 81.54% reduction in scour depth is achieved with the application of one collar at 0° and 15° angles of attack, while 43.8% and 45.2% reduction in scour depth is achieved with the application of two collars at 0° and 15° angles of attack. This research causes considerable reduction in construction cost of bridge piers.
