Popis:	In this study, problems involving steady infiltration from periodic channels in heterogeneous soils are considered. The problems are governed by a Richards's equation. To study the problems, the equation is transformed into a modified Helmholtz equation. The modified Helmholtz equation is then solved numerically by employing a Dual Reciprocity Method (DRM). The method is applied to solve infiltration in different types of heterogeneous soils. Numerical solutions in terms of suction potential are compared. The solutions indicate that soil layers produce jumps in values of the suction potential. The results also indicate that the soil type influence to the water content in the soil.
