A mathematical model of water flow and transport of chemical substances is presented in the paper. This model takes into account the influence of variable density and viscosity of water caused by variable solute concentration in soil. A solution of the problem of water flow and solute transport was sought using numerical methods. A finite elements method for solution of water flow equation and Monte-Carlo method to simulate solute transport were applied. Advantages of the presented model are illustrated on the example of water flow and salt transport in two dimensional ground profile in the region of Puck Bay. The geology of this profile is taken from Jankowska et al (1994). Obtained results from the proposed model are qualitatively conformable with observations in situ.
