Abstract
Transport of reactive chemical through fractured porous media is described by advection, dispersion, diffusion and sorption processes. Hence, an advective dispersive transport equation, including equilibrium sorption and first-order degradation coefficient, is considered for solute in the fracture and simultaneously a diffusive transport equation is considered for porous media. A numerical implicit finite difference method is used to solve the transport equation for solute in the fracture. Finally, numerical results of various temporal moments have been predicted to investigate the behaviour of reactive solute in the fracture. It was found that the behaviour of zeroth temporal moment, mean arrival time and second temporal moments are non-linear along the travel distance for solute in the fracture in the presence of matrix diffusion and decay rate coefficient. It was also seen that the higher values of matrix diffusion, retardation factor and decay rate coefficients reduce solute mass recovery in a fracture along the travel distance.
