| Abstract | : | In this work, a water flow analysis in heterogeneous soils is presented. Water flows from periodic trapezoidal channels into the heterogeneous soils. The heterogeneous soils consist of two layers, namely, Layer 1 and Layer 2. The flow follows Darcy’s law, which is then developed into Richards equation by Lorenzo A. Richards in 1931. To do an analysis of the water flow, Richards equation needs to be solved, by transforming the equation into a modified Helmholtz equation and then solved numerically. The numerical method used in this paper is a dual reciprocity method (DRM). Solutions are presented in terms of suction potential. A comparison of the values of suction potential in the heterogeneous soils and corresponding homogeneous soils is presented and discussed. |
