Abstract : In this paper, steady infiltration problems into homogeneous soil from a single trapezoidal channel with impermeable horizontal surface are considered. Homogeneous soils with and without impermeable layer are incorporated into the problems. These problems are governed by a Richards equation. To study the problems, the governing equation is transformed into a modified Helmholtz equation and solved numerically using a Dual Reciprocity Method (DRM). The method is implemented using MATLAB to obtain required numerical solutions or results. A comparison between numerical results obtained from one problem with those obtained from other problems are made. The numerical results indicate that up to a certain level of soil depth, the suction potentials obtained from the different problems considered are relatively same. From that level of soil depth, variations in values of suction potential are observed. For the soil without impermeable layer, values of suction potential decrease as the depth of soil increases. On the other hand, for the soil with impermeable layer, the results indicate that the closer location to impermeable layer, the higher values of suction potential.
