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.

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:
