Example of the MODFLOW Prescribed Concentration Boundary (PCB) Package dialog

The Prescribed Concentration Boundary (PCB) package is only used when there is a constant concentration boundary condition in the MODFLOW-USG Transport simulation.

A constant concentration boundary condition can be assigned to a the MODFLOW-USG Tranport model by using the MODFLOW/MT3DMS Source/Sinks dialog for either selected cells or in the conceptual model.

In the MODFLOW Prescribed Concentration Boundary (PCB) Package dialog, the following can be edited:

  • Stress period
  • Use previous
  • Edit All Use Previous
  • cell ID – Changing the cell ID will change which cell contains the concentration boundary.
  • Species ID – List which species has been assigned to the cell. Only values corresponding to existing species can be used.
  • Concentration – The concentration value assigned to the cell.
