Evaluating Scour at Bridges, Third Edition
This document contains revisions obtained from further scour-related developments and use of the 1993 edition of HEC-18 by the highway community. The principal change from the 1993 edition of HEC-18 is the use of metric (SI) units of measurement. Additional changes are: a discussion of backwater effects on contraction scour and the use of the water surface or the energy grade line as the reference line for measuring contraction scour depths, addition of a coefficient to the pier scour equation to account for the armoring effect of large particle sizes in the bed material, and addition of an equation of compute the coefficient applied to the pier scour equation when there is an angle of attack. This document includes a method to compute scour depths for pressure flow when a bridge deck is submerged. A discussion of computer models to determine the value of the hydraulic variables for scour analysis of bridges over tidal waterways has been added and information on scour detection equipment has been updated based on recent research.
