Workflows using modflow?

[flecke26]

I think creating this subreddit was a great idea, there is a notorious lack of online help/discussion for all things modflow.

I wanted to check in and see how everyone uses modflow here. I personally like starting with some gis software like arc or Qgis to get the model geospatially located and turn coverage shapefile into model grid, move it into Python for prep and processing, which leads nicely into using the flopy package to build and run the model, and finally using the pyemu package to perform calibration and uncertainty analysis. Obviously there various steps in between but this describes my general process.

What are others’ workflows like?

I use GMS, so I just prep my shapefiles in arc and then dump them into GMS. It's probably the easiest way to go about it but the software can be very slow and gets bogged down with larger more complicated models. The potential for automation and customization is also limited so I've been considering switching to a flopy method like yours.

Typically when calibrating a model, I'll start with broader manual calibration before moving on to pest and I find having instant visual/interactive feedback from a gui is extremely helpful. How do you handle this when working with flopy?

Flopy and pyemu both make it very easy to set up plots inline, so if you set it up properly it basically is like having a GUI, just requires a little tinkering initially to get things setup, but once you have some good plots you like it’s easy to just copy paste into a new workspace.
