Description:
pyTEF 0.1
pyTEF
pyTEF is a Python package that can be used to apply the Total Exchange Framework (TEF) to analyze the exchange flow of an estuary.
To do so TEF analyzes the exchange flow in salinity and/or temperature coordinates rather than spatial coordinates since the dynamics of most estuaries are controlled by the salt distribution. This package provides the necessary tools to use the TEF framework and is built on top of xarray.
Installing
To install use
git clone https://github.com/florianboergel/pyTEF.git and then
pip install -e pyTEF
How to use
00_tef_core.ipynb contains the TEF framework and all documentation.
01_calc.ipynb mainly contains the coordinate transformation of the transport terms and the calculation of the bulk values
Further you find different examples on how to use the TEF framework.
02_example_analytical.ipynb - validation of the pyTEF package
03_example_persian_gulf.ipynb - example TEF analysis applied to the Persian Gulf
Learn about TEF
The TEF analysis framework (Burchard et al., 2018; Lorenz et al., 2019; MacCready, 2011) allows a consistent calculation of the transports and salinities of an exchange flow in salinity space (or every other coordinate). The main idea of TEF is that transports of volume and salinity in and out the estuary of the same salinity partially compensate since only the net exchange changes salinity and volume of the estuary.
