DOI: 10.1002/vzj2.20055
Abstract: Preferential flow in soils contributes to water and contaminant leaching to groundwater and subsurface drains. At practical scales, preferential flow is often neglected due to the lack of consensus or guidance on how to simulate… read more here.

DOI: 10.1007/s10661-017-5977-4
Abstract: There are a large number of macropores/tubular channels of a few centimeters and plant roots in reclaimed dump soils, which are the main reasons for the formation of soil macropores and soil preferential flow. To… read more here.

DOI: 10.1016/j.hydromet.2017.06.008
Abstract: Abstract Heap leach stockpiles inevitably contain local voidage heterogeneities due to non-uniform particle size distributions of the ore and other factors that lead to preferential flow paths and solution channelling. The stockpile can also encounter… read more here.
