Experimental And Numerical Simulation Of Contaminant Transport Through Layered Soil
Abstract
In this study, the solute transport through saturated multi-layer soils was studied in the laboratory using the soil column experiment. Sodium chloride was used as a conservative chemical and sodium fluoride as a reactive chemical in the experiment. During the experiment, a pulse-type boundary condition was used. An implicit finite-difference numerical analysis was also carried out to get the numerical solution of advective–dispersive transport including equilibrium sorption and first-order degradation constant for the multi-layered soil. The results of experimental breakthrough curves (BTCs) showed that the order in which the soil layers were stratified in a water-saturated profile did not influence the effluent solute concentration distribution. The results also show the effect of column Peclet number, retardation factor, and first-order degradation coefficient on BTCs for the solute transport in multi-layered soils
