Working with graphical user interfases (GUIs) can be slow when one wants to do a severe trial-error runs on a groundwater flow model. Pumping test intepretation requires a lot of attemps in order to calibrate the steady and transient parameters as hydraulic conductivity, vertical anisotropy, specific storage and specific yield.
This tutorial show a procedure to generate the modflow files and run them by scripts in Python. The process allows to setup a generic model for a pumping test interpretation where the pumping rates, and observed head can come in separate files or arrays.
