Finite Element Modeling of Leaching from a Municipal Landfill
S.A. Mirbagheri and H.R. Kazemi Esfeh

The production of leachate from municipal sanitary landfills is an important environmental problem associated with solid waste management. In this study, a one dimensional mathematical model based on convection-dispersion equation in unsaturated porous media is presented to compute inorganic total solids concentration along the landfill. The numerical model is base on finite element method. A fortran77 computer program has been prepared for the model. The Source term in convection-dispersion equation is based on Straub and Lynch leaching generation term for inorganic total solids. Because of nonlinearity, a Picard method has been used. Moisture transport equation has been solved by LEACHW model. The model has been verifying by two experimental measurements. The model has been compared with the Demetracopoulos model. The K` value which is a rate coefficient in the model is very important term in contaminant transport equation in a landfill. The value of K` is obtained by experimental works. This model could be applied to field scale problems for the landfill management.
