HEC-18 Abutment Scour

About the Tutorial

This tutorial provides a step-by-step procedure on how abutment scour depth is calculated based on the 2012 FHWA publication of HEC-18. The method, which was recently added in DDMSW 5.6.0, employs a criterion in distinguishing a live-bed condition from a clear-water condition, and thus employing the appropriate approach to evaluate the scour depth.
