HEC-18 Pressure Flow Scour

About the Tutorial

This tutorial provides a step-by-step procedure on how scour depth from pressure flow is calculated based on the 2012 FHWA publication of HEC-18.  The evaluation of pressure flow scour for a bridge under inundation conditions is based on two stream scenarios: live-bed condition or clear-water condition. This method was not available in DDMSW 5.3.0 but has recently been added in DDMSW 5.6.0.
