Abstract

Mathematical model of the salt transfer during the non-stationary filtration and the moisture transfer in full and partial saturation soils layers including osmotic and infiltration phenomena is formulated. Numerical solutions of respective boundary problems are obtained by means of finite differences method. Proper software is developed using which numerical experiments and their analysis are performed.
