Abstract

In this paper, problems involving steady infiltration from periodic trapezoidal channels are considered. There are variations in the depth and width of the periodic channels. The governing equation of the problems, which is Richards equation, is transformed into a modified Helmholtz equation. The modified Helmholtz equation is then solved numerically using Dual Reciprocity Boundary Element Methods (DRBEM). Solutions obtained are then compared and discussed to observe effects of the depth and width of the channels to water content in the soil.
