Abstract
In this study, a two-dimensional numerical model for water flow and solute transport, Hydrus-2D, was used to investigate the impact of landfill cover thickness and the antecedent water content (Ө) of the soil beneath the landfill on the chloride percolation below the landfill. Series of simulation scenarios were performed using season varying climatic data during a 30-year period including two varying factors; thickness of landfill cover (0, 50, 100 cm) and the antecedent soil water content (0.12 and 0.20 m3m-3). The simulation results showed that maximum chloride concentration for different scenarios at all location within soil profile during the entire simulation period was less than the chloride concentration in the MSW leachate.

In this study, a two-dimensional numerical model for water flow and solute transport, Hydrus-2D, was used to investigate the impact of landfill cover thickness and the antecedent water content (Ө) of the soil beneath the landfill on the chloride percolation below the landfill. Series of simulation scenarios were performed using season varying climatic data during a 30-year period including two varying factors; thickness of landfill cover (0, 50, 100 cm) and the antecedent soil water content (0.12 and 0.20 m3m-3). The simulation results showed that maximum chloride concentration for different scenarios at all location within soil profile during the entire simulation period was less than the chloride concentration in the MSW leachate. In addition, as the landfill cover increased the concentration of chloride at a certain location decreased. Meanwhile, the time required to reach this location increased. The simulation results showed also that the impact of antecedent soil water content on chloride concentration reduction increase as the cover thickness increased. Based on the result, it was recommended to use a landfill cover to reduce the chloride concentration. Cover thickness of 50 cm is suitable in case of low antecedent soil water content. (Less)
