Abstract

AbstractGenerally, advection–dispersion and fractional advection–dispersion equations are used to model the transport of solute tracer in a porous medium. This study describes the numerical solution of both the general advection–dispersion equation and the space fractional advection–dispersion equation. The developed numerical model is used to simulate the observed data of chloride concentration obtained in the laboratory using soil column experiments. Different scenarios were used to estimate the transport parameters to simulate the concentration profiles through experiments.
