I. Introduction Electrical Resistivity Imaging (ERI) is a geophysical imaging technique used to visualize subsurface structures by measuring the ground’s electrical resistivity. This method involves injecting electrical current into the ground through a series of electrodes and measuring the resulting…

I. Definition and Principle of ERT Electrical Resistivity Tomography (ERT) is a geophysical imaging technique used to visualize subsurface structures by measuring the ground’s electrical resistivity. This method involves injecting electrical current into the ground through a series of electrodes…

Overview：Electrical Imaging uses measured electrical responses to build a model of subsurface resistivity. Electrical Resistivity Tomography (ERT) extends this principle into 2D or 3D imaging, while Vertical Electrical Sounding (VES) focuses on resistivity variation with depth at a selected location.…
