Abstract
In general, natural soils exhibit a spatial heterogeneity that may be important for the field-scale spreading of solute. One manifestation of spatial heterogeneity that is typical for the unsaturated zone is the existence of relatively large and more or less continuous voids. These voids are commonly referred to as macropores and may, for instance, be interaggregate pores, earthworm holes, drying cracks in clay soils, and decayed root channels. Such macropores are generally characterized by distinctly different soil hydraulic properties than the soil matrix and may result in rapid solute movement through the unsaturated zone.
