Design a Dam for Mill Tailings

Tailings dam failures can originate from overloads, anomalous behavior of the material used to build the dam (normally tailings), or from problems with the drainage mechanisms, which result in an increase of pore water pressure, and therefore a loss of resistance. They can also result from other things, like poor monitoring systems, for instance.
