In this paper, the tailings flow is regarded as a homogeneous and incompressible non-Newtonian fluid. The principles of dam safety apply at all stages of the life cycle (design, construction, operation, decommissioning, and long-term closure).

The main features, such as the outer wall slopes, may also be altered or flattened by erosion to the point that the facility is unrecognisable in comparison to its previous engineered state. Despite the development of tailings dam safety standards, guidelines, bulletins, risk assessment tools and management tools, tailings dam failures with high consequence have occurred at a similar rate over the last ten years as they did before. Implementing these guidelines would improve tailings dam safety, require respect for affected communities-including the right to say no to tailings dams-and hold mining companies legally and financially accountable for their actions. In order to address tailings dams and new dams, a revised edition was published in 1999 by the newly-formed Canadian Dam Association (CDA).
