Abstract
To enhance the scientific nature and the reliability of physical modeling of tailings dams, the present developments and main achievements are discussed from four perspectives: dam break, downstream evolution, stability evaluation and protection tests. The experiment materials, methods of measurement and instruments used are summarized. The problems and shortcomings of physical model tests are investigated in terms of the difference between a physical model and a prototype, nature of the experiment, methods of measurement, etc. Emerging technologies such as artificial intelligence and 3D printing to improve safety of tailings dams are discussed. The scope of the review embraces environmental impact of tailings dams in case of accidents.
