Abstract: Estimates of runout distance of liquefied tailings from a failed dam may use strength-based approaches 
using either rheological parameters, or the critical state concept of undrained steady state strength. 
Problems associated with selection of rheological parameters are discussed. It is proposed that a reasonable 
approach is the assumption usy s=τ  and 0=pη . Energy/work based methods are used as a check on this 
assumption and found to give good agreement. The effect of assumptions regarding the volume of material 
incorporated in the slide area is also investigated using the energy-based equations. The results indicate that 
there is a limiting volume, above which significant increases in the runout distance do not occur.
