HEC-18 Guide Bank Scour

About the Tutorial

This tutorial provides a step-by-step procedure on how guide bank scour depth is calculated based on the 2012 FHWA publication of HEC-18. The method, which was not available in DDMSW 5.3.0 but recently added in DDMSW 5.6.0, offers two options in evaluating the depth of scour: live-bed condition or clear water condition.  By providing the input data required, the program automatically selects which appropriate method is used.
