  abstract = {{W}e present an innovative hydrogeophysical approach for non-invasive quantification of the unsaturated water flow. {F}or the water content measurements, we apply the {M}agnetic {R}esonance {S}ounding ({MRS}) method in the time-lapse


mode. {F}or inversion of {MRS} measurements, we approximate the subsurface by a horizontally stratified media. {L}aterally, the {MRS} estimated water content is averaged over the area below the measuring setup. {D}uring this study, we


used a square loop of 75 m side-length. {T}he time-lapse inversion allows visualizing variations in the water content in the vadose zone down to twenty meters. {W}e tested our approach at the {V}illamblain test site ({F}rance). {F}or that,


we carried out the {MRS} monitoring in 1999-2000 and 2020-2021. {D}uring these two observation windows, {MRS} shows seasonal variations of the water content but also a strong dependence of the water content on the rainfall


that was different between two data sets. {C}omparison of {MRS} results with the rainfall records shows a good correspondence in-between. {F}or measuring and processing {MRS} data, we used commercially available {MRS} instrument


and interpretation software.},
