Subsurface Structure Mapping with GPR: Case Studies
Ground penetrating radar (GPR) is a non-invasive geophysical technique used to explore the subsurface structure of the Earth. This versatile tool emits high-frequency electromagnetic waves that penetrate into the ground, reflecting back from different strata. The reflected signals are then processed to generate images or profiles of the subsurface, revealing valuable information about buried objects, structures, and groundwater distribution.
GPR has found wide applications in various fields, including archaeology, civil engineering, environmental monitoring, and mining. Case studies demonstrate its effectiveness in identifying a variety of subsurface features:
* **Archaeological Sites:** GPR can detect buried walls, foundations, pits, and other structures at archaeological sites without disturbing the site itself.
* **Infrastructure Inspection:** GPR is used to inspect the integrity of underground utilities such as pipes, cables, and systems. It can detect cracks, leaks, voids in these structures, enabling timely repairs.
* **Environmental Applications:** GPR plays a crucial role in mapping contaminated soil and groundwater.
It can help assess the extent of contamination, facilitating remediation efforts and ensuring environmental sustainability.
