Abstract
In this paper, the modelling of contaminant transport through aquifers over a horizontal plane by the application of the vertex-centred edge-based finite volume scheme is presented. A complete description of the coupled set of equations and their discretisation is given, together with a description of the compact stencil model that is used in the implementation. The problems considered include convective-dispersive flow with or without pollutant decay under constant Darcy velocity flow conditions and a similar case where a slug of pollutant is injected for a finite time. The final set of problems considers the transient coupled flow of both groundwater and pollutant, which is again extended to include decay terms.
