Prediction of abnormal geological structures ahead tunnel drilling (ahead geological
prospecting) has become an essential routine work in the tunnel excavation, offering …

There have been major improvements in instrumentation, field survey design and data
inversion techniques for the geoelectrical method over the past 25 years. Multi-electrode …

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 …

Electrical resistivity of the soil can be considered as a proxy for the spatial and temporal
variability of many other soil physical properties (ie structure, water content, or fluid …

Water and mud inrush is one of the most important geohazards in underground engineering.
The paper presents a state-of-the-art review of the current understanding of this type of …

Direct current (DC) resistivity (here referred to as resistivity) and induced polarization (IP)
methods allow, respectively, the determination of the spatial distribution of the low-frequency …

We assess the usefulness of electrical resistivity tomography (ERT) in imaging and
characterising subsurface solute transport in heterogeneous unconfined aquifers. A field …

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 …

The fate of nano zerovalent iron (nZVI) during subsurface injection was examined using
carboxymethylcellulose (CMC) stabilized nZVI in a very large three-dimensional physical …
