For gravimetric lysimeters: Groundwater = Zero Poten6al Lysim. Boaom = Zero Poten6al

Fluxes are poten6al driven. Field matrix poten6al needs to be lysimeter matrix poten6al. We need to measure field condi6on and need to transmia it into lysimeters
11/5/13 TMS – Seminar 2013
We need to control the lower boundary condi6on to reach true hydraulic field situa6ons in lysimeters
