Abstract


Abstract. Governing equation of the problem involving infiltration in homogeneous soils is Richard's Equation. This equation can be studied more conveniently by transforming the equation to a modified Helmholtz equation. In this study, a dual-reciprocity boundary element method (DRBEM) is employed to solve the modified Helmholtz equation numerically. Using the solutions obtained, numerical values of the matric flux potensial are then computed. The proposed method is tested on problems involving infiltration from a single flat and trapezoidal irrigation channels in a homogeneous soil. The numerical solutions of both channels are then compared.
