Electrical resistivity tomography methods for archaeological prospection [PDF]

open access: yes, 2008
Two advanced applications of electrical resistivity methods in archaeological prospecting are presented. The approach is based on new inversion techniques, which enable the modelling of the resistivity distribution below any arbitrary topography.

ELECTRICAL RESISTANCE TOMOGRAPHY [PDF]

open access: yesThe Leading Edge, 2000
Electrical resistance tomography (ERT) is a method that calculates the subsurface distribution of electrical resistivity from a large number of resistance measurements made from electrodes. For in-situ applications, ERT uses electrodes on the ground surface or in boreholes. It is a relatively new imaging tool in geophysics.

Iterative geostatistical electrical resistivity tomography inversion

open access: yesHydrogeology Journal, 2023
AbstractElectrical resistivity tomography (ERT) is a geophysical method used to create an image of the subsurface due to its sensitivity to porosity, water saturation, and pore fluid salinity. This geophysical method has been widely applied in the investigation of mineral and groundwater resources, as well as in archaeological, environmental, and ...

Transdimensional Electrical Resistivity Tomography [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2018
AbstractThis paper shows that imaging the interior of solid bodies with fully nonlinear physics can be highly beneficial compared to imaging with the equivalent linearized tomographic methods and that this is true for a variety of different types of physics. Including full nonlinearity provides interpretable uncertainties and far greater depth of image

Smart Water Meter Using Electrical Resistance Tomography [PDF]

open access: yesSensors, 2019
Smart flow monitoring is critical for sewer system management. Obstructions and restrictions to flow in discharge pipes are common and costly. We propose the use of electrical resistance tomography modality for the task of smart wastewater metering. This paper presents the electronics hardware design and bespoke signal processing to create an embedded ...

Using electrical resistivity tomography to evaluate the relationship between groundwater potencial and tectonism in northeast Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2021
The relationship between groundwater potential and tectonic conditions in three sectors of clastic and carbonated sedimentary rocks of northeastern Mexico was identified using electrical resistivity tomography performed in seven transects.
