2022-10-26 11:00 AM 2022-10-27 03:00 PM Atelier sur l’analyse de bris de barrages de digues à résidus miniers N.A. America/New_York

11am ET to 3pm ET | 9am to 1pm MT | 8am PT to 12 noon PT

In this 2 half-day virtual workshop, you will deepen your competencies for conducting tailings dam breach analyses, based on the Tailings Dam Breach Analysis Technical Bulletin, that the Canadian Dam Association (CDA) published in 2021. The Tailings Dam Breach Working Group (WG) who prepared the Technical Bulletin is very excited to give this special training course.

Designed for dam safety professionals who wish to expand their knowledge about tailings dam failures and dam safety professionals who wish to gain a better understanding of the CDA Tailings Dam Breach Analysis Bulletin, this course will focus on the tailings dam specific issues and challenges that are critical to capture in such studies, which become more apparent from some of the recent catastrophic tailings dam failure. 

Participants will gain clarity on how to use and apply the key steps outlined in the Technical Bulletin. Specifically, attendees will learn about: 

This is an interactive workshop where attendees will be welcome to share their experiences.

About the TBDA Technical Bulletin 

The Technical Bulletin provides a process and outlined key steps for conducting analyses as well as the hydrotechnical, geotechnical, rheological and modelling aspects that are relevant for these analyses. The objective is to promote the science of tailings dam breach analyses and build awareness on the risk of tailings dam failures.
