Weill, S., et al. « Coupling Water Flow and Solute Transport into a Physically-Based Surface–Subsurface Hydrological Model ». Advances in Water Resources, vol. 34, no 1, janvier 2011, p. 128‑36. DOI.org (Crossref), https://doi.org/10.1016/j.advwatres.2010.10.001.

This example shows how to use pyCATHY object to plot inputs of the hydrological model.

Estimated time to run the notebook = 5min
