The Fundão Tailings Dam failed on November 5, 2015 in a liquefaction flowslide that initiated at the dam’s left abutment. This Investigation was performed to determine its cause.

In structuring its investigation process, the Panel systematically identified and evaluated multiple causation hypotheses. It further imposed hypothesis testing by means of the following three questions that the candidate failure mechanism should be able to explain:

After reviewing the results, a sensitivity analysis was commissioned to understand the impact of a number of model input parameters on the predicted subsidence limits. This document is presented as an addendum to the original report, documenting the results of this sensitivity analysis.

This technical memorandum was prepared to document preliminary results of fate and transport modeling using additional seepage controls to reduce seepage rates developed for Resolution Copper (RC) tailings storage facility (TSF) alternatives.

The IFTDSS Planning cycle is designed with the fuels management employee in mind.

A number of tailings storage facility (TSF) designs are currently being assessed and will be included in the draft EIS (DEIS). This report presents Alternative 4 - Silver King Filtered.

This report represents a state-of-the-art synthesis of current knowledge of the ecology and hydrology of ephemeral (dry washes) and intermittent streams in the American Southwest.
