Discover how modern geophysical surveys help locate groundwater before borehole drilling begins. This presentation explains the Electrical Resistivity Test, how electrical measurements reveal underground geological formations, and how 2D resistivity imaging supports aquifer identification. Learn the step-by-step process, including site analysis, field profiling, data logging, and 3D inversion and modeling. Understand how scientific groundwater exploration can reduce the risk of dry wells and support better borehole site selection for a reliable long-term water supply.
