Abstract/Additional Information

• Failure modes of a tailing dam. Discussion of recent tailings dam failures.
• Use of Tailings Dam Tool and regression equations to estimate volume releases. 
• Simulate tailings dam breach including tailings material and water volume using a two-phase flow model.
• Predict downstream mudflow inundation.
• Simulate mudflow – fluid exchange with scour and deposition, downstream tributary inflow and mudflow into lakes and reservoirs.
• Predict sediment routing by size fraction, and mudflow cessation and re-mobilization.
• Set up a project using QGIS and the FLO-2D model. Application of the Tailings Dam Tool.
• Mudflow Hazard Mapping.

Key Takeaways: 
• Understand potential failure modes of tailing dams.
• Learn about basic data and key factors for tailing dam failure modeling.
• Simulate tailing dam failures using a two-phase flow model.
• Review mapping and analysis of results.
