It is well known that there is a spectrum of pores in a soil profile. The conventional use of a single lumped value of soil hydraulic conductivity to describe a spectrum of hydraulically active pores may have unintentionally impeded the development o

Field experiments were conducted on tile-drained plots at the South East Purdue Agricultural Center in Butlerville, Indiana, to quantify contaminant transport via preferential flow paths in a silt loam soil. Breakthrough patterns of three fluorobenzo

Solute concentration and soluble dye studies inferring that preferential flow accelerates field-scale contaminant transport are common but flux measurements quantifying its impact are essentially nonexistent. A tile-drain facility was used to determi

Soil-solution sampling methods developed more than 50 yr ago are still routinely used to monitor the fate of contaminants in unsaturated soils. The measured results, expressed as a function of depth or time, are called breakthrough curves (BTC). In t
