Most larger bridge piers are complex in shape. This adds to the difficulty in predicting local sediment scour depths at these structures. A methodology for estimating current-induced, equilibrium local scour depths at structures that are composed of up to three components is presented in this report. Even though bridge piers come in different shapes and sizes many consist of a pile group, a pile cap or footer, and a structure above the pile cap referred to in this report as a column. The methods discussed in this report can be applied to structures with one or more of these components. The procedure is based on laboratory data obtained at the Federal Highway Administration Turner Fairbanks Laboratory in McLean, Virginia and in the Hydraulics Laboratory at the University of Florida in Gainesville. The portion of the total scour produced by each pier component is computed and the results summed to produce the total design scour depth. Additional data are currently being obtained so that the procedure can be extended and improved.
