摘要：

A series of laboratory tracer migration experiments in a single rock fracture have been performed, and the breakthrough curves have been interpreted using mathematical modelling. Discrepancies were observed between the experimental data and the predictions made using a simple advection-dispersion model. The potential reasons for these discrepancies have been investigated by applying more complex models: one model incorporates channelling of flow within the fracture, the other couples dispersion and advection in the fracture with rock-matrix diffusion. It is concluded that channelling of flow can adequately explain the observed spreading behaviour; rock-matrix diffusion is not a significant mechanism influencing transport in these experiments.
