Transfer Function Model on Chloride Transport in Heterogeneous Saturated Soils under Steady Flow

  • The experiments were done for the purpose of analyzing saturated solute transport in the heterogeneous soil.Two kinds of heterogeneous soil columns (48cm×48cm×40cm) were irrigated with 0.027 Mol/L CaCl2 solution when steady flow occurred in the soils.The breakth rough curves data were obtained.The parameters of the model were calculated,and the probability density functions of the logarithm of travel time of chloride were derived.In addition,the simulated data of breakthrough curve of the chloride in heterogeneous soil were computed using the transfer functionm odel.Finally,the transport volumes of Cl-,mobile volume and the volume-averaged concentrations in the soil solution were estimated.
