Modelling transport in reacting geochemical systems

Reactive transport modelling is a powerful tool for analysing a broad variety of problems involving the migration of fluids through the Earth's subsurface. In this paper we consider the behaviour of this class of numerical models and show how they might be applied in one dimension to improve our understanding of the interaction between transport and reaction processes. The examples we present demonstrate both the potential of the models and the challenges that arise in applying them.
