Abstract
Preferential flow is a useful generic term for describing the process whereby water and chemical movement through a porous medium follow favored routes bypassing other parts of the medium. This term does not give any indication of the pore scales involved. Sometimes macropore flow is used to describe preferential flow and this term implies that large pores of some sort are conductive. There is no consensus definition of what constitutes a macropore so one may need to carefully determine what is meant when that term is used.
