MECHA is an explicit cross-section model of the root hydraulic anatomy which connects hydraulic concepts across scales.

The model computes horizontal water flow at the level of individual cells, quantifies the contribution of water composite pathways, and predicts root radial permeability (kr), using detailed anatomical descriptions and experimental data on the permeability of cell walls (kw), membranes (Lp) and the conductance of individual plasmodesmata (KPD).

MECHA can be tried online here:

MECHA was developed at the Université catholique de Louvain, in the Earth and Life Institute, in the lab of Xavier Draye. The primary developers of the model are Valentin Couvreur and Marc Faget.
