Nov 11-13, 2025: ON Branch: HEC-RAS (1D-2D) Training 2025
When: November 11-13, 2025
Where: Conference Center in Sheridan College, Trafalgar Campus, Oakville, ON
Description:
The CWRA Ontario branch will be hosting a 3-day in-person HEC-RAS training course, on 11th to 13th November, 2025 in the Conference Center in Sheridan College, Trafalgar Campus, Oakville, ON. The training will be delivered by the International Water Training Institute.
Led by experienced trainer and modeller Krey Price, the course will balance theory with hands-on workshops to help participants build, run, troubleshoot, and interpret both 1D and 2D HEC-RAS models.
What you’ll learn:
- Setting up HEC-RAS projects and preparing GIS data
- Creating and editing 1D and 2D geometry files
- Entering flow data, boundary conditions, and running plans
- Troubleshooting model stability and sensitivity
- Calibrating results and comparing with measured data
- Preview of upcoming HEC-RAS capabilities, including pipe networks
By the end of the course, attendees will be able to develop and animate basic flood models from scratch and apply practical skills to their own projects.
Lunch and morning/afternoon coffee, tea and snacks are included in registration.
Group registration: Available for groups of 4+ from the same organization. A separate registration link will be provided upon request to manager@cwra.org or on@cwra.org.
