Continuity in pressure between two adjacent intervals

Good morning,
I have a piece of soil above a water table at depth equal to z = -3.3m.
In order to don't have any problem regarding the water pressure limit at water level, I decide to split the domain in two interval:
interval 1: from z=0 (reference for the water table in COMSOL) to z=0.5m interval 2: from z=0.5m to z=3.3m
I have two different Richards' equations with two different pressures (pl1 and pl2). I set the upper limit for pl2 max = 0kPa at groundlevel.
But in order to have continuity in the water pressure distribution between the two intervals how can I do?
Because I put a precipitation at Ground level that in someway influences the interval related to the waterlevel; but I have the default setting about "NO FLOW" in the intersection that linked the two intervals and I don't know how to overcome or, at least, replace this condition.
Thanks to all
