Groundwater is under pressure from climate change, urban expansion, and agricultural demand. Sustainable management requires understanding not only how much water exists, but also how it flows and how vulnerable aquifers are to contamination. While drilling provides...
Ground-Penetrating Radar (GPR) transmits electromagnetic pulses into the ground and records reflections from subsurface boundaries. These reflections are governed by contrasts in dielectric permittivity, which vary between materials such as soil, rock, metal, and...
Near-surface investigations are no longer limited to trial pits and drilling. Over the past two decades, geophysics has reshaped how engineers, planners, and archaeologists understand the subsurface. Instead of isolated samples, geophysical surveys provide continuous...
