Thanks to all who attended our sold-out course in Wellington. For those who were unable to attend, we’ll be returning to NZ with an upcoming course in Auckland 8-9 Nov 2017. Please register your interest to be kept informed of any other upcoming NZ courses.

Following a successful round of 2D flood modelling and dam break courses in New Zealand in 2016 and 2017, we have now completed our first course in Wellington which was held in the Tonkin + Taylor offices in Wellington.

Pricing is just NZD $800 for our full 2D flood modelling courses. Registration discounts are available for members of selected professional organisations, including ANCOLD, NZSOLD, EA, and IPENZ. Please enquire for coupon codes to apply at checkout. Select “Direct Bank Transfer” at checkout and we will generate an invoice that can be paid in NZD. For those paying by credit card, the transaction will be in AUD using today’s exchange rate to convert to NZD.



This course focusses on 2D flood modelling, including terrain manipulation and hydraulic structures. We will also include a brief introduction to dam breach parameters. 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 evacuation order to downstream population centres after an earthquake-induced landslide dam blocks an upstream valley.

The course runs from 8:30 am to 5:00 pm. Following is an outline of the course proceedings:
