Pastas: Analysis of Groundwater Time Series
[!IMPORTANT]
As of Pastas 1.5, noisemodels are not added to the Pastas models by default anymore. Read more about this change here.
Pastas: what is it?
Pastas is an open source python package for processing, simulating and
analyzing groundwater time series. The object oriented structure allows
for the quick implementation of new model components. Time series models
can be created, calibrated, and analysed with just a few lines of python
code with the built-in optimization, visualisation, and statistical
analysis tools.

Quick installation guide
To install Pastas, a working version of Python 3.9, 3.10, 3.11, or 3.12
has to be installed on your computer. We recommend using the Anaconda
Distribution as it includes most of
the python package dependencies and the Jupyter Notebook software to run
the notebooks. However, you are free to install any Python distribution
you want.
