Breaching parameters for earth and rockfill dams

, 2009
Dam risk analysis is at the heart of dam failure prevention and mitigation. In order to assess dam risk, it is essential to conduct a quantitative analysis of the process of a dam breach, which can be described by such parameters as breach geometry ...

Numerical analysis of strengthening by rockfill embankments on an upstream tailings dam

, 2013
The consolidation process could be slow in an upstream tailings dam; therefore, the stability can reduce due to an increase in excess pore pressures when the dam is raised.
