Please join us in Auckland in June 2018 for an intensive, interactive course using free hydrologic and hydraulic modelling software:

* Learn rainfall-runoff and flood routing with HEC-HMS

* Build, run, and animate 1D and 2D hydraulic models using HEC-RAS

Come find out what’s new in HEC-RAS 5.0.4 in the first New Zealand course covering these powerful new features:

  • Variable time steps
  • New culvert options
  • Mesh refinement regions
  • Internal boundary conditions
  • Access faster computation speeds
  • And more!

Previous Auckland Courses

Following the success of our inaugural HEC-RAS 5.0 course in Australia, we were pleased to have The RAS Solution and Breaking the HEC-RAS Code author Chris Goodell return to the southern hemisphere to teach a sold-out dam breach analysis course in Auckland in 2016. We held additional 2D flood modelling courses in Auckland, Christchurch, Wellington, Manukau, Parnell, Devonport, and Raglan in 2017, and we plan to hold additional courses in 2018 subject to interest levels.

In light of the recent Kaikoura Earthquake, we have added an exciting case study in which you have one hour, working as a team from scratch, to use HEC-RAS to decide whether or not to send the order to evacuate downstream population centres after an earthquake-induced landslide dam blocks an upstream valley.
