Abstract

The problem of two-dimensional nonsteady flow of water in unsaturated and partly saturated porous media is solved by a Galerkin-type finite element approach. Special emphasis is placed on the treatment of atmospheric boundaries, water uptake by plants, irregularly shaped boundaries, soil heterogeneity, and soil anisotropy. The apparent advantages of this method over more conventional numerical techniques are discussed.
