Abstract: A problem involving time-dependent infilltration from periodic channels with root-water uptake is governed by Richards equation. To study the problem numerically, the governing equation is transformed into a modified Helmholtz equation using the Kirchhoff transformation, dimensionless variables, and Laplace transforms. The modified Helmholtz equation is then solved numerically using a dual reciprocity boundary element method (DRBEM) and a predictor-corrector scheme simultaneously. A numerical inverse Laplace transform is employed to obtain numerical solutions of the problem.
