Electrical Resistivity Tomography (ERT) is a geophysical method designed to image subsurface structures by measuring how soils and rocks resist electrical current. It has become a vital tool in geology, engineering, and environmental science because it provides non-invasive insights into underground conditions. By placing electrodes on the ground surface and recording voltage differences, researchers can create two-dimensional or three-dimensional models of resistivity distribution. These models reveal variations in soil moisture, rock type, and groundwater presence. Unlike traditional drilling, ERT offers a cost-effective way to cover large areas without disturbing the environment. Its versatility makes it suitable for diverse applications, ranging from groundwater exploration to archaeological investigations. As technology advances, ERT surveys are increasingly integrated with remote sensing and machine learning, enhancing accuracy and interpretation. Thus, ERT represents a modern, sustainable approach to understanding the hidden layers beneath our feet.

ERT surveys employ several electrode configurations, each tailored to specific subsurface conditions. The Wenner array, with equally spaced electrodes, provides strong vertical resolution, while the Schlumberger array allows deeper penetration by spreading current electrodes farther apart. Dipole–dipole arrays are particularly sensitive to lateral changes, making them effective for detecting faults or contamination plumes. For broader coverage, pole–dipole and pole–pole arrays reduce the number of electrodes required. Beyond array choice, ERT can be conducted in two-dimensional lines, three-dimensional grids, or even within boreholes for deep investigations. Time-lapse ERT, where surveys are repeated over time, is used to monitor dynamic processes such as groundwater recharge or landslide movement. Each method balances resolution, depth, and efficiency, and the choice depends on project goals. Together, these techniques provide flexible options for imaging subsurface structures with remarkable detail and reliability.

The importance of ERT lies in its ability to provide detailed subsurface information without invasive excavation. In groundwater studies, it helps locate aquifers and determine water table depth, which is critical for sustainable water management. In engineering, ERT ensures that foundations are built on stable ground by identifying weak zones, cavities, or fractured bedrock. Environmental scientists rely on it to detect contamination plumes, monitor landfill sites, and assess soil degradation. Archaeologists use ERT to uncover buried structures without disturbing cultural heritage sites. Moreover, ERT supports disaster risk reduction by monitoring slope stability and predicting landslide-prone areas. Its non-invasive nature makes it environmentally friendly, while its adaptability across disciplines highlights its universal relevance. By bridging science, engineering, and conservation, ERT plays a crucial role in safeguarding resources, infrastructure, and ecosystems, making it indispensable in modern geoscience and environmental management.
