  abstract: A computer model was developed to describe the simultaneous movement of eight interacting ions in a soil-water system. The effects of cation adsorption, ion-pairing, convective transport, molecular diffusion, and hydrodynamic dispersion were included in the model. The development of the model was carried out in the following three phases: (a) investigation of five finite-difference approximations to the linear, one-dimensional, convection-diffusion equation, (b) development of a Newton-Raphson procedure for solving the system of equilibrium equations associated with the eight ions, (c) development of a system of finite-difference equations to describe the movement of the eight ions and the effect of certain model parameters on simulated ion concentration pulses. The explicit scheme, Chaudhari's scheme, Bresler's scheme, Stone and Brian's scheme, and a second-order explicit scheme were compared with respect to efficiency and accuracy in solving the one-dimensional convection-diffusion equation. A new method for analyzing the behavior of central-difference equations was suggested..
