| Abstract | The report provides a user guide for a mathematical model describing transport and fate processes in laboratory scale model aquifers. Such model aquifers are constructed to evaluate strategies for the reclamation of groundwater contaminated with nitrates and other pollutants. The mathematical model can be used for evaluations of strategies for injecting chemicals, which could enhance pollutant degradation, into an aquifer. The model allows calculation of hydraulic pressure field and perturbations of the field by injection and/or extraction wells. It uses the pressure field to compute the Darcy velocities, which in turn are used in computing the chemical transport and fate. The model is LT3VSI, which handles four chemicals and two microbial populations. |
