We have seen that the greatest limitation of the resistivity sounding method is that it does not
take into account horizontal changes in the subsurface resistivity. A more accurate model of …

The growing interest in the maintenance of favorable soil structure is largely motivated by its
central role in plant growth, soil ecological functioning, and impacts on surface water and …

Details of Earth's shallow subsurface—a key component of the critical zone (CZ)—are
largely obscured because making direct observations with sufficient density to capture …

We want to develop a dialogue between geophysicists and hydrologists interested in
synergistically advancing process based watershed research. We identify recent advances …

This paper reviews the recent geophysical literature addressing the estimation of saturated
hydraulic conductivity (K) from static low frequency electrical measurements (electrical …

Appropriate regularizations of geophysical inverse problems and joint inversion of different
data types improve geophysical models and increase their usefulness in hydrogeological …

There is increasing interest in the use of multiple measurement types, including indirect
(geophysical) methods, to constrain hydrologic interpretations. To date, most examples …

Essentially all hydrogeological processes are strongly influenced by the subsurface spatial
heterogeneity and the temporal variation of environmental conditions, hydraulic properties …

This review covers, in a comprehensive manner, the approaches available in the literature to
upscale soil water processes and hydraulic parameters in the vadose zone. We distinguish …

Studying the forest subsurface is a challenge because of its heterogeneous nature and
difficult access. Traditional approaches used by ecologists to characterize the subsurface …
