How Geophysical Methods Support Sustainable Groundwater Management
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 direct information, the cost and limited coverage make it unsuitable as the primary…
Ground-Penetrating Radar: What It Can (and Cannot) Detect
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 concrete. When GPR works extremely well GPR is ideal for high-resolution imaging in dry, resistive ground…
How Near-Surface Geophysics Reveals What Traditional Methods Miss
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 lateral coverage, offering a far more detailed picture of soil layers, bedrock, voids, utilities, and…

Highlight: Practical field course
Do you want to learn how to find archaeological remains using advanced methods such as ground penetrating radar, magnetometer, geoelectric measurements and professional metal detectors?
During April–May 2026, we will organize a practical field course and present the book “Before Digging – A Practical Guide to Geophysical Investigations in Archaeology”.
In consultation with local archaeologists, we plan to hold one-day courses in most counties in southern and central Sweden.
Register your interest by January 30, 2026 and receive a 30% discount on the field course, the book and a practical compendium of the methods.
