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 …

In hydrothermal systems associated with volcanic areas, the flow of groundwater generates
an electrical current of electrokinetic nature, the so-called streaming current. This current is …

Low-frequency geoelectrical methods include mainly self-potential, resistivity, and induced
polarization techniques, which have potential in many environmental and hydrogeological …

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

Seawater intrusion into onshore aquifers represents a significant environmental threat
worldwide especially in this new era of climate change and sea water rise. This is the case …

ERT and SP investigations were conducted in carbonate rocks of the Dinant Synclinorium
(Walloon Region of Belgium) to find suitable locations for new water wells in zones with little …

Excessive rainfall is considered the major landslide triggering mechanism, especially in
tropical climate regions. During rainfall, water infiltrates into the subsurface; reducing the …

In hard-rock aquifers, fractured zones constitute adequate drinking water exploitation areas
but also potential contamination paths. One critical issue in hydrogeological research is to …

We describe the use of a fully volumetric geophysical imaging approach, three-dimensional
electrical resistivity (3D ERT), for bedrock detection below mixed sand and gravel deposits …

We propose an algorithm to invert self‐potential signals measured at the ground surface of
the Earth to localize hydromechanical disturbances or to the pattern of groundwater flow in …
