Solute Transport In Two Layered Porous Media (Separated Diagonally) Using Suitable DQM Scheme

Abstract

In this research, we presented Differential Quadrature Method for solving groundwater flow and advection-dispersion equations in two layered porous media which the layers are separated diagonally. This method was applied to five cases and the results are compared with Modflow and Mt3d solutions. Also, The effect of various parameters on transport process are discussed in all cases. The DQM results show a good agreement with Modflow and Mt3d results regarding selecting fewer grid points. In applying the DQM, the needed mesh size is much smaller than the traditional approaches which reduces computational time and needed less computer storage capacity.
