Detection of Water-Table by Using Ground Penetration Radar (GPR)

Engineering and Technology Journal, 2011
Ground penetrating radar, GPR, is a high resolution geophysical method, which is based on the propagation of high frequency electromagnetic waves. The GPR method images structures in the ground that are related to changes in dielectric properties. In sediments, water content primarily causes the changes in dielectric properties.
