The Matrix Diffusion Transport package (MDT) works with MODFLOW-USG Transport. The MDT package allow existing flow and chemical transport models of sites to include a full accounting of matrix diffusion effects. The package works with the BCT process.
The MDT Package dialog is divided into two parts: one on the left which shows the main sections, and one on the right which shows the inputs for the current section.
Comments
Comment lines can be added and will appear at the top of the MDT file. Use the Add Row 
button to create comments. Comments can be removed using the Delete Row 
button.
