Supporting data – Limits to the Estimation of Old Streamwater in Catchments Using Environmental Tracers

# Supplementary Jupyter Notebooks for "Limits to the Estimation of Old Streamwater in Catchments Using Environmental Tracers" This repository contains illustrative Jupyter notebooks that can be used to generate some basic results, figures, and analyses presented in the paper: > **Limits to the Estimation of Old Streamwater in Catchments Using Environmental Tracers** > Raphaël Miazza and Paolo Benettin > Institute of Earth Surface Dynamics, Université de Lausanne, Switzerland > _Submitted, 2025_ > https://doi.org/10.22541/essoar.174461783.34658765/v1 --- ## Contents `01_critical_age_sine_wave.ipynb`: Computes the critical age for a sinusoidal tracer input. `02_arbitrary_TTD_tails.ipynb`: Computes arbitrary tails for a reference transit time distribution, and convolves them with a sinusoidal tracer input. --- ## Environment Setup We recommend using a Python virtual environment (e.g. conda) for reproducibility. The notebooks require the following Python libraries (as well as their dependencies):- Numpy (https://numpy.org/)- Scipy (https://scipy.org/)- Matplotlib (https://matplotlib.org/)
