Abstract

Soil serves as a puros medium through which pollutants can be transported top to the deeper layers. Additionally, the movement and dispersion of salts and pollutants within the soil are influenced by soil moisture conditions, such as saturated or unsaturated, as well as the velocity of the flow. The present research aimed to monitor the behavior of water and chlorine in the soil columns containing montmorillonite clay layers and to simulate salt movement across the soil profile under the pilot conditions. To this end, in columns characterized with 150 cm in height and 15 in diameter containing loamy sand soil, treatments with and without clay layers with thicknesses of 13 and 20 cm were embedded. The columns were washed with ammonium nitrate, applying 13 and 20 mEq/l potassium chloride, then the volume and concentration of chlorine drainage, breakthrough curves and simulation of chlorine concentration in soil profile were performed. The results of this study showed that increasing the thickness of the clay layer was well prevented the drainage. In addition, the concentration of chloride in the outlet stream positively correlated with the thicker clay layer and higher salt concentration. The predicted results showed similar results in comparison with the observed data. In charts with a thicker clay layer, chlorine concentrations reached the rates much faster. For the other two treatments, this increase was lower. According to the results, the coefficient of determination (R2) for chlorine in the soil column was between 0.87 and 0.92, indicating the ability of the model to yield an acceptable simulation.
