Application of Electrical Resistivity Tomography for Detecting Root Biomass in Coffee Trees

open access: yesInternational Journal of Geophysics, 2013
Roots play an important role in plants and are responsible for several functions; among them are anchorage and nutrient and water absorption. Several methodologies are being tested and used to study plant root systems in order to avoid destructive root ...

Predicting the movements of permanently installed electrodes on an active landslide using time-lapse geoelectrical resistivity data only [PDF]

open access: yes, 2010
If electrodes move during geoelectrical resistivity monitoring and their new positions are not incorporated in the inversion, then the resulting tomographic images exhibit artefacts that can obscure genuine time-lapse resistivity changes in the ...
