Abstract

Modern computational techniques enable, in principle, the modeling of transport in porous media, involving convection, adsorption and dispersion. Implementation of the techniques for practical problems leads to various difficulties, however. One of these is the difference in horizontal and vertical scales in natural situations; other difficulties encountered are numerical dispersion and the flow near singularities. In order to overcome these difficulties a two-dimensional flow model has been adapted to incorporate three-dimensional velocity components. This procedure takes into account that in regional flow fields the horizontal flow components in aquifers are much larger than the vertical components, and yet it enables to observe transport in vertical direction. Numerical dispersion is suppressed by particle tracking.
