Summary This paper deals with the competition between effects during miscible displacements through heterogeneous permeability media. Displacements with an even front are dispersive, others are a type of bypassing: fingering, caused by an adverse mobility ratio, or channeling, caused by heterogeneity and autocorrelation. Under most flow circumstances, channeling is the predominant type.
