ADGeo (not expiring license)
Analysis of pollutant spread in a phreatic aquifer – ver.2 (english version)
ADGeo allows to simulate the transport of pollutants in a phreatic aquifer taking in account the vertical direction too (Verruijt, 1993). Solution is obtained through by finite element method in case of multilayered soil characterized by variability of the hydrogeological parameter.
The cumulative effect of the dispersion and adsorption of a pollutant inside the porous medium is inserted in the calculation through a numerical procedure called random walk (Feller, 1966).
