INSTRUCTOR:
J. Erik McCarthy, PE, CFM
*Should one of the above instructors be unavailable to teach, a qualified WEST Consultants instructor will be appointed to replace him.
This is a hands-on seminar. You must bring your own laptop.
Purpose and Background
This intensive, hands-on, two-day seminar and computer workshop will prepare the engineer and water resources professional to use HEC-RAS for one-dimensional (1D) steady flow analysis in real-world situations. Led by experts with experience in hydraulic modeling, participants learn how to compute water surface profiles, analyze bridge and culvert hydraulics, and conduct floodplain information studies using the 1D steady flow capabilities of HEC-RAS. Unsteady flow and two-dimensional (2D) modeling are not covered in this course.
HEC-RAS capabilities for 1D steady flow analysis include:
- Analysis of subcritical, supercritical, and mixed flow regimes
- Bridge and culvert hydraulic analysis
- Bridge scour analysis, including contraction, pier, and abutment scour (not covered in this course)
- GIS pre- and post-processing using RAS Mapper
HEC-RAS is one of the most extensively tested civil engineering computer programs ever developed. In addition to in-house testing at the U.S. Army Corps of Engineers Hydrologic Engineering Center, the program has been tested by thousands of engineers in the private and public sectors.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Explain how to use the U.S. Army Corps of Engineers HEC-RAS (River Analysis System) program for 1D steady flow analysis
- Apply HEC-RAS through hands-on practical computer workshops
- Explain hydraulic principles for rivers, waterway bridges, and culverts
- Improve the effectiveness of future flood-control or drainage projects
- Use RAS Mapper to perform GIS pre- and post-processing
- Explain the basic modeling principles for developing 1D steady flow hydraulic models
- Identify the three main components of a 1D steady flow HEC-RAS model
- Explain the theoretical basis of 1D steady flow computations in HEC-RAS
- Develop 1D steady flow HEC-RAS models for analyzing confluences and bridge/culvert structures
Assessment of Learning Outcomes
The instructor(s) will assess student performance during multiple computer workshop problems. You will also take a test after completing the class, with questions addressing these learning outcomes.
Special Features
Approximately five days before class, participants will receive an email with links to the HEC-RAS software, PDFs of the course slides and workshop solutions, and input files for the workshops.
Who Should Attend?
Consulting engineers, water resource planners, and engineers employed by local, state, and federal government agencies. Participants should have some experience in floodplain hydrology and/or hydraulics and should be familiar with the Windows operating system. No prior HEC-RAS experience is required.

How to Earn your CEUs/PDHs
This webinar is worth 1.4 CEUs/14 PDHs. To receive your certificate of completion, you will need to complete a short post-test in class and receive a passing score of 70% or higher.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
