Electrical Resistivity Tomography (ERT) is a widely used geophysical technique that enables scientists, engineers, and environmental specialists to image subsurface conditions without excavation. The method works by injecting a controlled electrical current into the ground through electrodes and measuring the resulting voltage differences. These measurements are processed to determine the electrical resistivity of underground materials, which varies according to factors such as soil type, rock composition, moisture content, porosity, and fluid conductivity. ERT surveys generate detailed two-dimensional (2D) or three-dimensional (3D) models that help visualize subsurface features with remarkable accuracy. Because it is non-invasive, cost-effective, and environmentally friendly, ERT has become an essential tool in modern geophysical investigations. The technique offers valuable insights into hidden geological structures and supports informed decision-making across many scientific, environmental, and engineering applications worldwide.

One of the most important applications of Electrical Resistivity Tomography is groundwater exploration and hydrogeological assessment. Water-bearing formations often exhibit distinct resistivity characteristics that can be identified through ERT surveys. By mapping variations in subsurface resistivity, geophysicists can locate aquifers, determine groundwater depth, estimate aquifer thickness, and distinguish between fresh and saline water zones. This capability is particularly valuable in regions facing water scarcity, where efficient groundwater resource management is essential. ERT also assists in identifying recharge zones, fracture systems, and pathways for groundwater movement. Compared to conventional drilling methods, resistivity surveys provide broader subsurface coverage while reducing exploration costs and risks. As global demand for clean water continues to rise, ERT plays a vital role in supporting sustainable water resource development and improving the success rate of groundwater exploration projects.

In engineering and construction projects, Electrical Resistivity Tomography serves as a powerful site investigation tool. Before major infrastructure developments such as buildings, highways, railways, bridges, dams, and tunnels are constructed, engineers need accurate information about subsurface conditions. ERT helps identify variations in soil and rock properties, detect weak zones, locate cavities, and estimate bedrock depth. The technology is especially useful for evaluating ground stability and minimizing unforeseen geological hazards that could affect project safety or increase construction costs. Because ERT provides continuous subsurface imaging between boreholes, it complements traditional geotechnical investigation methods and enhances site characterization. Engineers can utilize the resulting resistivity models to optimize foundation design, improve risk assessment, and ensure long-term structural performance. Consequently, ERT has become an increasingly valuable component of modern geotechnical and civil engineering practices.
