The location and shape detection of water-bearing structures, such as karst caves and faults,
is significant for water inrush early warning during tunnel construction. The direct current …

The degradation of mountain permafrost is well documented at many Alpine sites.
Geophysical techniques have been intensively used to monitor these sites, since permafrost …

In the absence of quantitative relationships, a cross-gradient function can be used to
correlate unknown physical properties in a joint inversion of geophysical data sets. It …

Structural joint inversion of several data sets on an irregular mesh requires appropriate
coupling operators. To date, joint inversion algorithms are primarily designed for the use on …

Cross-gradient joint inversion that enforces structural similarity between different models has
been widely utilized in jointly inverting different geophysical data types. However, it is a …

Full waveform inversion (FWI) of ground penetrating radar (GPR) is a promising technique to
quantitatively evaluate the permittivity and conductivity of near subsurface. However, these …

We present a novel joint inversion strategy for electrical resistivity tomography (ERT) and
seismic first-arrival traveltime data with guided fuzzy c-means (GFCM) clustering coupling to …

The resistivity imaging method, an effective geophysical technique, has been widely used in
environmental, engineering and hydrological fields. The inversion method based on smooth …

This paper proposes an approach for the joint inversion of gravity and magnetic data using
Gramian constraints to address the non-uniqueness of the inverse problem. The Gramian …

As a method with high resolution, GPR has been extensively used in archaeological
surveys. However, conventional GPR profile can only provide limited geometry information …
