This tutorial will describe how to extract data from HEC-RAS to conduct an HEC-18 analysis using the Federal Highway Administration's (FHWA's) Hydraulic toolbox.
FHWA provides this brief overview of the bridge scour capabilities in the toolbox:
Some practitioners have developed their own tools and spreadsheets for this analysis.
This tutorial provided guidance on how to extract the correct data from HEC-RAS for any of these approaches, but we will focus on parameterizing the official Hydraulic Toolbox.
This toolbox performs many transportation related calculations, but we will only use the Bridge Scour tool in this tutorial. Press the bridge scour button or go to Calculators→ New Bridge Scour Analysis. Then click on the Bridge Scour Analysis region node in the Project Explorer
