Time of travel through compacted soil liners is difficult to predict because numerous factors confound the analysis. In this paper, the influence of spatial variability and uncertainty on the time of travel is considered. A second-order approximation to the Kramer-Moyal probabilistic equation of motion is employed to obtain the time-of-travel distribution. The solution is presented in terms of an isorel chart and dimensionless parameters. An example problem is presented to illustrate how the reliability is computed.
