Effect of Nonlinear Adsorption on Contaminant Transport in Aquifer

using a one-dimensional advection–diffusion model. The numerical analysis was conducted under the assumption of the square-pulse response measurement at the output in a column experiment. The analysis showed the rejoins of the model parameters that nonlinear adsorption was unable to approximate the linear adsorption equilibrium. We need to evaluate the contaminant transport phenomena using nonlinear in that region.
