ABSTRACT
A soil water model of one dimensional flow, using the Runge-Kutta Gill
algorithm, is described with the aim of forming a flexible general purpose
simulation tool. The problem of ‘stiffness’ appearing in the traditional
finite difference methods approach is discussed, and a numerical algorithm
able to overcome it is adopted. The model, based on a flexible numerical
approach, is tested with published data. The tests show the model performance
to be satisfactory in soil water simulations. The performance of the numerical
algorithm is compared with that of a number of alternative numerical methods.
The comparison supports the original choice of the algorithm.
