Abstract
A computer based numerical approach for the analysis of the movement of water in unsaturated one-dimensional soil water systems is described. The development of the relevant finite difference equations and the form of the solution analogue are summarized together with details of the initial conditions and boundary conditions. The program structure is then outlined and the analysis of the treatment of nonhomogeneous profiles is briefly described. The latter chapters in the report cover input data presentation, parameter definition and three examples of typical soil water problems.
