MODFLOW-LGR Regional to Local Workflow

To quickly create a local model coupled to the regional model using MODFLOW-LGR (with either a transient model or a steady state model), use the following process:

1. Begin with an existing MODFLOW project.
The existing model should be created using the conceptual model approach.

2. Change the simulation to use MODFLOW-LGR.
Select MODFLOW | Global Options. In the MODFLOW Global/Basic Package dialog, select the LGR radio button.

3. Create a child grid.
Use the Select Cells tool to drag a box in the child grid area. Right-click in the selected area and select Create Child Grid…. Enter child grid parameters in the Create Child Grid dialog.

4. Save and run MODFLOW-LGR.
Save the project. Run MODFLOW .
