In this paper, the soil columns(repacked sieved sandy loam, different dry density, 15.3 cm diam.×50 cm long)were irrigated at constant ponded infiltration intensities with a step-change in NaCl solution. The transfer function model(TFM)developed by Jury et al(1982)was used for simulating chloride travel through the soil columns during steady, saturated water. The transport parameter values for the soils were determined by TFM(with an assumed lognormal distribution of travel times). The simulations were tested against experimental values of drainage effluent concentration. In addition, the characteristic values of convective transport of chloride in soils were analyzed.
