The Cadia tailings dam, owned by Newcrest and in New South Wales Australia, failed on March 9, 2018. Extensive geological investigations, including drilling and sampling activities to characterise the site, laboratory tests, both routine and advanced, were performed to determine the range of properties exhibited by these materials, and Advanced numerical simulations of both deformation behaviour and ultimate failure states were computed to validate the hypotheses of the cause(s) of the Event under consideration.
