Short summary
A tailings dam is an earth embankment used to store the waste from mines, known as tailings. In 2019, the Brumadinho tailings dam in Brazil failed, releasing a mudflow which killed ~ 300 people. This paper details the use of an agent-based model to estimate the risk to people downstream of this dam. The agent-based model represents each individual person. The modelling indicated that if a warning had been issued as the dam failed, the number of fatalities could have been reduced.
