Geophysics provides a multidimensional suite of investigative methods that are transforming
our ability to see into the very fabric of the subsurface environment, and monitor the …

We explore and review the value of soil moisture measurements in vadose zone hydrology
with a focus on the field and catchment scales. This review is motivated by the increasing …

The current paper complements the review of the status of the effort toward commercial gas
production from hydrates. We aim to describe the concept of the gas-hydrate (GH) petroleum …

Scientific curiosity, exploration of georesources and environmental concerns are pushing
the geoscientific research community toward subsurface investigations of ever-increasing …

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 …

The self-potential method enables non-intrusive assessment and imaging of disturbances in
electrical currents of conductive subsurface materials. It has an increasing number of …

Technological and methodological progress is essential to improve our understanding of
fundamental processes in natural and engineering sciences. In this paper, we will address …

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

Interactions between groundwater (GW) and surface water (SW) have important implications
for water quantity, water quality, and ecological health. The subsurface region proximal to …

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 …
