Abstract:

The paper presents a class of models that are well-suited for microcomputing and that are based on what may be called the 'Matched Aritifical Dispersivity' method. The method is applicable to flow and transport phenomena described by parabolic governing equations. Typical one-dimensional examples are the advection-dispersion (A-D) equation governing the transport of a conservative solute in a flow system with constant mean velocity and the so-called 'linear diffusive wave' flood routing model.
