The paper concerns effective conductivity of a heterogeneous soil composed of two materials characterized by different hydraulic conductivities. According to the homogenization theory the effective conductivity is obtained from the solution of an elliptic equation for a single representative elementary volume. A numerical algorithm to solve this equation is described. Examples of calculations for periodic media with inclusions of various shapes are presented. Influence of volumetric fraction, arrangement, continuity and conductivity ratio of the two materials on the effective conductivity is investigated. Numerical results are compared with some analytical estimations available in the literature.
