Preferential flow paths at decimeter and smaller scales are pervasive in the heterogeneous geological media. Recent studies have shown that they exert a dominating control on solute transport. However, their characterization in the field and the incorporation into solute transport models have been a significant challenge. This presentation will review the recent advances in field techniques and model development that have improved our ability to characterize and predict solute transport in highly heterogeneous aquifers containing small-scale preferential flow paths and relative flow barriers.
