Abstract

In order to accurately model chemically reactive transport, one needs to incorporate ome type of grid adaptivity into the numerical simulator. In this paper we give an example fa two-component contaminant transport model, which exhibits some interesting physical henomena and motivates our desire for grid adaptivity. A dynamically adaptive method ? then developed in the context of a Godunov-mixed method for a scalar equation. heoretical and numerical results for this approach are presented. Introduction "he accurate modeling of chemically reactive transport in a porous medium > crucial to monitoring and remediating contaminant sites. Over the past everal years, mathematical and numer
