The Principal Direction Technique: A New Approach to Groundwater Contaminant Transport Modeling

  • E. O. Frind
Conference paper

Abstract

The problem of contaminant transport in long thin hydrogeologic systems is investigated and a new simulation technique based on Galerkin finite elements, but formulated in terms of the principal directions of transport and structured as an alternating direction solution scheme, is applied. It is shown that the new technique is both more accurate and more efficient than the conventional finite element technique. The accuracy is unaffected by an extreme geometric aspect ratio or a large contrast between the physical parameters in different directions.
