Oct 29-30, 2026: BC Branch: HEC-RAS 2D Modeling Workshop
When: October 29-30, 2026
Where: Metrotower I, M100 Meeting Room (Ground Level), 4710 Kingsway, Burnaby, BC V5H 4M2
Description:
The CWRA BC branch will be hosting a 2-day in-person HEC-RAS training course, on 29th and 30th October, 2026. The training will be delivered by experienced trainer and modeller Gaven Tang, the course will balance theory with hands-on workshops to help participants build, run, troubleshoot, and interpret both 1D and 2D HEC-RAS models. The course topics are summarized below.
Lunch and morning/afternoon coffee, tea and snacks are included in registration.
