Acquisition of soil solute transport parameters is a precondition for predicting solute transport using the numerical model in practice. A new and simple method is recommended here for estimating transport parameters of D and R using changes in depth of the solute front with time by means of one order approximate solution of CDE (Convective dispersive equa tion, CDE). Time domain reflectometry (TDR) was used to determine the time when the solute front arrived at different fixed points in the soil column and at the same time effluent from the column was collected for parameters estimation with the BTC (Breakthrough curve, BTC) fitting method using the CXTFIT program at the bottom of the soil column. By comparison the retar dation factors, R, derived with the two methods are more or less the same, however the convective dispersive coefficient D esti mated with the solute front information method is generally smaller than the one with the BTC fitting method. One of the factors resulting in the smaller D is the lag of the measured solute front behind the theoretic one, which is testified by comparing the for mer with the latter calculated using the parameters figured out with the BTC fitting method. Comparison between the measured BTC and the calculated BTC shows that the two have the same dispersive process in sand soil and the same times soil solute made the initial breakthrough and complete breakthrough, which demonstrates that the parameters estimated based on solute front information is somewhat applicable, but the precision of this method need further improvement.
