spowtd: Scalar parameterization of water table dynamics

Spowtd provides a Python module and script to analyze water table time series in settings where the behavior of the water table is essentially determined by the current precipitation and evapotranspiration.

Docs

For now, see the PDF user guide in Docs. For usage hints, just type:

$ spowtd

Bugs

• Currently the script does not check if the previous steps required to do a new step have been completed or not. So, you may get a cryptic error message if, for example, you try to plot the recession curve if the recession curve has not been assembled yet.

Build and install

Build: python3 setup.py build

Test: ./check_errors.sh

Install: python3 setup.py install

Build dependencies

Spowtd is built for Python 3.

Use of the spowtd command-line tool or library requires:

• python3
• python3-matplotlib
• python3-numpy
• python3-pytz

The following packages are required for the build and tests:

• asciidoc
• pdflatex
• python3
• pylint-3 (python3-pylint)
• pytest-3 (python3-pytest)
• python3-scons

For development, you may additionally want:

• python3-pycodestyle
• python3-coverage
• python3-pytest-cov
