Over the last 15 years significant advancements in induced polarization (IP) research have
taken place, particularly with respect to spectral IP (SIP), concerning the understanding of …

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

A model combining low‐frequency complex conductivity and high‐frequency permittivity is
developed in the frequency range from 1 mHz to 1 GHz. The low‐frequency conductivity …

The complex conductivity of soils remains poorly known despite the growing importance of
this method in hydrogeophysics. In order to fill this gap of knowledge, we investigate the …

I developed a new model named POLARIS describing the complex conductivity of (pyrite‐
free) shaly poorly sorted sands. This model is based on the solution given by the effective …

There is growing interest in the use of geophysical methods for hydrological model
parameterization. Empirical induced polarization (IP)–hydraulic conductivity (K) …

The electrical properties of near-surface geomaterials have been hugely important in the
development of many modern welldeveloped countries, and will play a leading role in the …

Microorganisms participate in a variety of geologic processes that alter the chemical and
physical properties of their environment. Understanding the geophysical signatures of …

We have compared various induced polarization (IP) models for permeability prediction of
the same general form that were all based on two parameters, the first being an electric …

Electric polarization is described as the sum of charge accumulations (free charge density)
and orientation of polar molecules such as those of bound and free water molecules (bound …
