About

Whether you're an experienced modeller looking to refresh your skills, or a beginner seeking structured, practical guidance, this course will walk you through the full process of setting up, running and mastering HEC‑RAS models.

Across a series of 8 hands-on practical sessions, you’ll learn how to create a model from scratch, organise your project files effectively, build and edit geometry, apply inflows and boundary conditions, and troubleshoot common errors. You'll gain confidence in running simulations, interpreting results, and exporting outputs for reports and further analysis.

Ideal for those wanting a practical, end-to-end understanding of HEC‑RAS modelling, from fundamentals through to results communication.

Course Overview

This course is designed to provide a blend of essentials and advanced training to enhance your expertise in HEC-RAS. Throughout these 8 sessions, participants will learn to develop basics through to advanced knowledge and skills as our expert presenters step you through the principles and outputs of the latest version of HEC-RAS, through real-world case study scenarios.

Topics covered

  • Overview RAS 6.7 vs RAS2025
  • File management and folder structure
  • Creating a basic 1D geometry and 2D flow area with advanced options
  • Flow and plan files with model validation and calibration
  • Hydraulics Structures (culverts/embankment data)
  • Extracting energy losses and rating curves
  • Troubleshooting model results and running sensitivity analyses
  • Advanced Export Options (maps with RASter calculator scripts; 3D Viewer; CAD/GIST for flood mapping)

Prerequisites

There are no formal perquisites, although we recommend attendees are familiar with basic hydrology and hydraulic concepts. For a refresher, our Hydrology &Hydraulics Essentials Series is available for on-demand attendance.

Completion

  • Attendees earn 16+ CPD hours/points (i.e. with Engineers Australia).
  • On completion of the course attendees will be issued with a Certificate of Participation.

 

Although the course’s tutorial models will be in version 6, we will also provide some previews of the new RAS 2025 interface; watch this video for a sneak peek:
