Abstract

Here dual reciprocity boundary element method is used for the analysis of pollutant dispersion in porous media. In the governing dispersion equation, the time dependent term and convective terms are approximated using dual reciprocity method and Green's theorem is used to form boundary integral equations. Linear elements are used for boundary discretization. The model is verified with one dimensional analytical solution and found to be satisfactory. The model is applied for the solution of some two dimensional pollutant dispersion problems in homogeneous isotropic porous media. Introduction In any development and management of groundwater resource system, a major problem of interest is that of the quality of the water being extracted. For the assessment of groundwater quality, it
