Abstract
Monte Carlo GRW simulations of passive transport in groundwater are used to investigate ergodic properties, dependence on initial conditions, and the occurrence of anomalous diffusion. It is shown that memory effects produced by dependence on initial conditions are responsible for the lack of ergodicity of the transport, in the sense of approach to the theoretical upscaled process. Evolving scale heterogeneity of groundwater systems, consisting of a superposition of spatial scales, enhances the memory effects and may explain the occurrence of anomalous diffusion behavior.
