FloPy

A Python package to build, run and post-process MODFLOW-based groundwater models, including MODFLOW 6, MODFLOW-2005, NWT and USG, as well as MODPATH, MT3DMS and SEAWAT. Instead of entering data in a graphical interface, you define the grid, layers, boundary conditions and wells in code, so it is easy to change parameters, run many scenarios and document the model. It complements MODFLOW 6 and ModelMuse. It requires familiarity with Python and MODFLOW.
