Description

We quantitatively compare models of root architecture and function. Simple benchmark scenarios test individual components of the complex models, such as root architecture, water flow in soil and roots, solute transport in soil and roots. More complex benchmark scenarios test the fully coupled systems.

Progress

The description of the benchmark problems has been published (Schnepf et al. 2020); the actual comparison between numerical results by different groups who implemented those benchmark problems in their models is ongoing. The progress can be seen at this GitHub repository: https://github.com/RSA-benchmarks/collaborative-comparison.
