The method of temporal moment solutions (MOM) for one-dimensional convective–dispersive solute transport involving linear equilibrium sorption and first-order degradation for time pulse sources has been applied to analyze experimental data from a soil microcosm reactor. Estimation of the pore water velocity V for a nonreactive solute was aided by the use of only the first normalized moment while the dispersion coefficient D, first-order degradation rate constant λ, and the retardation factor R… Expand

Application of the method of temporal moments to interpret solute transport with sorption and degradation.
TLDR
The method of temporal moment (MOM) formulae was applied to analyse breakthrough data from a laboratory column study of atrazine, hexazinone and rhodamine WT transport in volcanic pumice sand, as well as experimental data from the literature, finding that the MOM fitted breakthrough curves with tailing better than curve fitting.
