MT3DMS Is a modular three dimensional transport model that can be coupled with Modflow to simulate the concentration changes of miscible contaminants in groundwater considering different processes like advection, dispersion, diffusion and some chemical reactions.

By studying how the contaminants behave in groundwater we can determine influence areas and use this information in prevention plans to reduce contamination in order to achieve a sustainable management of aquifers.

In this tutorial we will show how to set up a MT3DMS in simple ModelMuse model in order to evaluate the degradation of the contaminant coming from a source.
