nlmod

nlmod is a Python package to build, run and visualize MODFLOW 6 groundwater models in the Netherlands. The main focus is on building models in the Netherlands using publicly available datasets, though lots of functionality could be applied to groundwater models elsewhere.

nlmod relies heavily on the wonderful features of xarray and geopandas for storing and manipulating data and flopy is used for building and running groundwater models.

We thank the following institutions for their contributions to the development of nlmod:

Please note that the documentation for nlmod is still a work in progress, so bear with us if certain aspects are incomplete.
