Following our free webinar covering best practices in tailings dam failure assessments (link below), this Premium Webinar provides further details designed to improve your tailings dam breach assessments.

Join us straight after the free webinar for a presentation of optimised workflows, guided by an expert panel of software developers responsible for keeping modelling programs up to date with the latest advances in non-Newtonian fluid modelling.

Full outline below.

Webinar Overview

The following topics will be covered in this Premium Webinar:

  • Considerations for selection of Bingham, Herschel-Bulkley, and other non-Newtonian flow models;
  • Selection of appropriate value ranges for yield strength, viscosity, and other rheological parameters;
  • Breach formation times and geometries;
  • Model sensitivity and calibration of model results to historical failures;
  • Interpretation of laboratory data and relevance to modelling parameters.

The webinar will present commonly adopted parameters based on measured laboratory data and observed failure events, focusing on the relationship between viscous stresses and turbulent/dispersive stress used in 2-phase flow simulations.


The presentations will be followed by live Q&A with the expert panel, including developers of HEC-RAS, TUFLOW, FLO-2D, FLOW-3D, and other models. Premium Webinar attendees will also receive access to additional pre-recorded bonus content from individual software developers.


Part 1 is free to attend and runs from 9:00 am to 9:50 am Sydney time; following a 10-minute break, the Premium Webinar – Part 2 (register from this page) runs from 10:00 am to 11:00 am Sydney time.
