The water content (θ) of the subsoil is an important parameter affecting all the processes that
occur in the vadose zone, playing a key role in the infiltration, aquifer recharge, and flow and
transport of water and substances, as well as groundwater storage. Although the vadose
zone is usually considered constituted of soil, it may also be comprised of rock. In the latter
case, θ cannot yet be operationally measured despite its unquestionable importance. The
