modflow-setup 0.4.0

Rapid and robust construction of MODFLOW groundwater flow models

Modflow-setup

Modflow-setup is a Python package for automating the setup of MODFLOW groundwater models from grid-independent source data including shapefiles, rasters, and other MODFLOW models that are geo-located. Input data and model construction options are summarized in a single configuration file. Source data are read from their native formats and mapped to a regular finite difference grid specified in the configuration file. An external array-based Flopy model instance with the desired packages is created from the sampled source data and configuration settings. MODFLOW input can then be written from the flopy model instance.

Version 0.4

Getting Started

For more details, see the modflow-setup documentation

Using a yaml-aware text editor, create a configuration file similar to one of the examples in the Configuration File Gallery.

The yaml file summarizes source data and parameter settings for setting up the various MODFLOW packages. To set up the model:

from mfsetup import MFnwtModel, MF6model

m = MF6model.setup_from_yaml(<path to configuration file>)

where m is a flopy MODFLOW-6 model instance that is returned. The MODFLOW input files can be written from the model instance:

m.simulation.write_simulation()

MODFLOW-NWT version:

m = MFnwtModel.setup_from_yaml(<path to configuration file>)
m.write_input()
