What is the main limitation of Ground Penetrating Radar (GPR)?
A. Poor resolution
B. Not effective in dry sand
C. High cost
D. Ineffective in conductive soils
Answer: Option D
Solution (By Examveda Team)
GPR struggles in highly conductive soils like clays due to rapid signal attenuation.It performs best in dry, sandy, or resistive environments.This Question Belongs to Geological Engineering >> Geophysical Methods In Engineering
