The vertical variability of soil moisture in the rootzone is a key factor and it is not taken into account in manyhydrological models.Therefore it is here proposed a novel approach that is based on the inversion of a semianalytical solution of theequation governing the infiltration and the exfiltration processes. The inversion allows keeping the informationcontained in the vertical spatial variability. It has been monitored with TDR measurements down to 2 metersdepth.Also, the hysteresis and dynamical effects are then taken into account, with water potential measurements, inorder to correctly predict the water retention both in infiltration and in drainage/exfiltration transients.

Abstract
The vertical variability of soil moisture in the rootzone is a key factor and it is not taken into account in manyhydrological models.Therefore it is here proposed a novel approach that is based on the inversion of a semianalytical solution of theequation governing the infiltration and the exfiltration processes. The inversion allows keeping the informationcontained in the vertical spatial variability. It has been monitored with TDR measurements down to 2 metersdepth.Also, the hysteresis and dynamical effects are then taken into account, with water potential measurements, inorder to correctly predict the water retention both in infiltration and in drainage/exfiltration transients.
