Electrical Resistivity Tomography
Electrical Resistivity Tomography (ERT) is where the resistance of ground layers is measured.

ERT data is collected by inducing current into the ground between electrodes, and the potential difference is then found using a different pair of electrodes. In the field, a series of electrode pairings are planted in the ground at regular intervals within the test area and are connected to a central control unit. ERT can generate a 1D sounding, as well as 2D or 3D profiles.
ERT has many applications and can be used for projects including:
