Unsaturated hydraulic behaviour of a permeable pavement

Hello everyone,

I want to implement hydraulic behaviour of a permeable pavement with COMSOL Multiphysics. This facilities normally drain freely through its base when they are saturated, while they are unsaturated no flux goes out from them. My doubt is how can I implement with the software this boundary condition at the bottom of the permeable pavement : the bottom acts as a "zero pressure head boundary" when it is saturated and as a "no flux boundary" when it is unsaturated.

I would be very grateful for your help.
