In the last two decades, shallow geophysics has considerably evolved with the emergence
of 2D spatial imaging, then 3D spatial imaging and now 4D time and space imaging. These …

We describe in this paper the theoretical background for the electrokinetics in rocks and in
porous media, to be included in the special issue “Electrokinetics in Earth Sciences” of …

Surface-based ground penetrating radar (GPR) and electrical resistance tomography (ERT)
are common tools for aquifer characterization, because both methods provide data that are …

The self-potential (SP) method is a passive geophysical method based on the natural
occurrence of electrical fields on the Earth's surface. Combined with other geophysical …

Cross‐hole radar tomography is a useful tool for mapping shallow subsurface electrical
properties viz. dielectric permittivity and electrical conductivity. Common practice is to invert …

The understanding of the streaming potential in partial water saturation conditions in porous
media is of great interest for the interpretation of spontaneous polarization observations. We …

The hydrogeological properties and responses of a productive aquifer in northeastern
Switzerland are investigated. For this purpose, 3D crosshole electrical resistivity tomography …

The interpretation of electromagnetic anomalies associated with volcanic activity requires a
good understanding of two rock properties, the electrical conductivity and the streaming …

The self‐potential (SP) method has long been used for a variety of geophysical applications
because of its ease of acquisition, but has suffered from difficulty in interpretation of the data …

The electrokinetic potential results from the coupling between the water flow and the
electrical current because of the presence of ions within water. The electrokinetic coefficient …
