The goal of my project is to simulate plant growth depending on atmospheric forcing (precipitation or evaporation) using the Feddes root-water uptake model.
Include a root hydraulic head depending root function into the Flow-source function. It is also possible to include more simple root configurations for future use.
What I want for my project are three connected functionalities of which only one calculates the sink term. It is called Root. The first of the other two uses the water uptake to calculate biomass production (used for root and shoot growth) called Biomass while the second uses the upper boundary condition and the shoot biomass to calculate the potential transpiration for the next time-step and is called Shoot.
(possibly as arrays to enable multiple plants in the future)

This is my first Issue so please inform me about what I information I should add or clarify.
