Oct 29-30, 2025: SK Branch: 2D HEC-RAS Training
When: October 29-30, 2025
Where: Holiday Inn Downtown, 101 Pacific Avenue, Saskatoon, Saskatchewan
Description:
- This will be a 2-day in-person HEC-RAS course focused on 2D analysis. Following a review of 1D analysis, the course will cover the development of a 2D model. Day 2 will cover more advanced topics with a focus on applications used in flood hazard mapping.
- Some experience with HEC-RAS is required.
- The course is restricted to in-person participation with a maximum of 25 participants.
- Following the course, participants will be emailed a certificate of completion for use in reporting to their professional association(s).
- The course will run from 8:30 AM to 4:30 PM daily.
- Participants will be required to provide a laptop with HEC-RAS Version 6.6 pre-installed.
- Outlets will be available for charging.
- Lunch and break refreshments will be provided.

Bio
Mr. Gaven Tang, M.A.Sc., P.Eng. (SK, AB, BC), is the Group Manager of Senior Professionals for WSP Canada’s Water Resources Engineering Group of 60+ staff in the Prairies and North Region. With over a decade of experience, he also serves as a Principal River Engineer and Project Manager specialising in flood modelling, inundation mapping, hazard assessments, and flood mitigation design. His portfolio includes 15+ flood hazard studies in Alberta (major studies include: Bow and Elbow Rivers, Fort McMurray, Red Deer, and Crowsnest Pass); a third-party flood mapping review for 15 Saskatchewan communities; and debris-flood mitigation engineering for Exshaw Creek and Jura Creek. He also contributed river hazard modelling and mapping to the Fraser Basin Council’s flood risk assessment for BC’s Lower Mainland. Mr. Tang holds a Master of Applied Science in Hydrotechnical Engineering from the University of British Columbia, where he developed a 2D mobile-bed dam-break model using TELEMAC2D and SISYPHE to simulate the historic Malpasset dam failure—demonstrating his deep expertise in hydrodynamic and morphodynamic modelling.
