Abstract

This particular finite element method is used to simulate the nonsteady flow of water in a multidimensional soil-plant environment. The approach can handle nonuniform soils having irregularly shaped boundaries and arbitrary degrees of local anisotropy. The soil can be unsaturated, saturated, or partly saturated. Flow can take place in a two-dimensional region or in a three-dimensional region having a radial symmetry. Particular emphasis is placed upon the simulation of atmospheric boundaries and water uptake by plant roots. The nonlinear atmospheric boundary conditions are handled by a unique iterative procedure relying on the ease with which fluxes normal to the boundary are assigned in the finite element approach. An example is included describing two-dimensional flow in a complex field situation. Refs.
