Electrical Resistivity Tomography (ERT): Understanding Its Use in Geophysical Surveys

What is Electrical Resistivity Tomography (ERT)? Electrical Resistivity Tomography (ERT), also known as electrical resistivity imaging (ERI), is a geophysical method used to determine the electrical resistivity distribution of the subsurface. By measuring resistivity variations, it is possible to generate a detailed resistivity profile of the underground environment. This technique is widely used in geotechnical […]

Douglas Partners acknowledges Australia’s First Peoples as the Traditional Owners of the Land and Sea on which we operate.

We pay our respects to Elders past and present and to all Aboriginal and Torres Strait Islander peoples across the many communities in which we live, visit and work. We recognise and respect their ongoing cultural and spiritual connection to Country.
