Application of electrical resistivity tomography (ERT) for rock mass quality evaluation [PDF]

Scientific Reports, 2021
AbstractRock mass quality evaluation is a challenging task in geotechnical investigations given the natural heterogeneity and the limited data. These investigations mainly depend on the traditional drilling tests. However, such tests are expensive and time consuming, provide point measurements, and cannot be conducted in steep topographic areas, and ...

Effects of machinery trafficking in an agricultural soil assessed by Electrical Resistivity Tomography (ERT)

Open Agriculture, 2018
Abstract Soil compaction is a serious problem, which is aggravated due to its difficulty to locate and reverse. Electrical resistivity tomography (ERT) is a non-invasive geophysical method that can be used to identify compacted areas, soil horizon thickness and assess soil physical properties. This study assesses the relationship between

Improving electrical resistivity tomography interpretation with Gray Level Co-Occurrence Matrix textural attributes [PDF]

Scientific Reports
Electrical resistivity tomography (ERT) provides valuable subsurface structural information but often relies on inverted resistivity thresholds for interpretation. Inversion inherently produces smooth boundaries that can lead to interpretation ambiguity,

Improved characterisation and modelling of measurement errors in electrical resistivity tomography (ERT) surveys [PDF]

Journal of Applied Geophysics, 2017
Measurement errors can play a pivotal role in geophysical inversion. Most inverse models require users to prescribe or assume a statistical model of data errors before inversion. Wrongly prescribed errors can lead to over- or under-fitting of data; however, the derivation of models of data errors is often neglected.

4D electrical resistivity tomography (ERT) for aquifer thermal energy storage monitoring [PDF]

Geothermics, 2019
Abstract In the context of aquifer thermal energy storage, we conducted a hydrogeophysical experiment emulating the functioning of a groundwater heat pump for heat storage into an aquifer. This experiment allowed the assessment of surface electrical resistivity tomography (ERT) ability to monitor the 3D development over time of the aquifer thermally ...
