answer:Try giving Wikipedia a spin: GPR has many applications in a number of fields. In the Earth sciences it is used to study bedrock, soils, groundwater, and ice. Engineering applications include Nondestructive testing (NDT) of structures and pavements, locating buried structures and utility lines, and studying soils and bedrock. In environmental remediation it is used to define landfills, contaminant plumes, and other remediation sites. In archaeology it is used for mapping archaeological features and cemeteries. It is used in law enforcement for locating clandestine graves and buried evidence. Military uses include detection of mines, unexploded ordnance, and tunnels. Before 1987 Frankley Reservoir in the UK was leaking 540 litres per second. In that year Ground-penetrating radar was used successfully to isolate the leaks.
