Electrical Resistivity Tomography (ERT) - from Zero to Hero • Session 2: Resistivity Surveying • How a resistivity survey is performed • How to calculate apparent resistivity • What is geometric factor • Description of array • A quick look at different resistivity surveys (1D, 2D, 3D and 4D) • • The presentation file is available at: • https://drive.google.com/file/d/19bnD... • Watch the whole video series (playlist) step by step to have a solid background on ERT, even if you are somehow familiar with it. There are some important points in each one. • I have got some emails asking what is the rule of ERT in studying the subsurface if we have to check it against geology, etc.?? . Two simple factors can be mentioned for this necessity: (1) the problem of non-uniqueness , and (2) checking the correctness of our primary assumptions.
