The influence of the double‐diffusive process of fingering on vertical transport in a porous medium is examined, using a very successful model borrowed from oceanic salt finger theory. The results suggest that fluxes associated with double‐diffusive fingering may well be important, at least in regions where the porous medium is saturated. The effect of horizontal dispersion remains to be accounted for and will probably place limits on the efficiency of the process.
