mf6rtm 0.1.3

Reactive transport model through MODFLOW 6 and PHREEQCRM

MF6RTM: Reactive Transport Model via the MODFLOW 6 and PHREEQCRM APIs

Benchmarks

Benchmark comparing model results against PHT3D are in benchmark/. Each folder contains a Jupyter notebook to write and execute an MF6RTM model via the MUP3D class. Additionally, PHT3D files are provided in the corresponding pht3d directory for each example.

Considerations

The current version is intended to work with structured grids (dis object in MF6) and one MF6 simulation that includes the flow and transport solutions. No support is currently provided for a 'flow then transport scheme,' meaning that advanced packages cannot be incorporated yet.

On the PHREEQC side, the following have been included:

• Solution
• Equilibrium phases
• Cation Exchange
• Surface Complexation
• Kinetic Phases

Most options for each phreeqc block can be passed by adding list with options. However, not all options had been tested, so please create an issue if any option is not working or crashing the model.

Software requirements

All dependencies and executables are included in this repo. This package extensively uses modflowapi and phreeqcrm

Installation
