Electrical Resistivity Surveys

It is used for measuring the electrical resistivity Distributions in the subsurface medium by injecting an electric current through a pair of electrodes into the ground and measuring the potential difference through another pair of electrodes to detect the subsurface geological layers, geotechnical problems, and groundwater aquifers.

.

Transient ElectroMagnetic (TEM) Technique

TEM method detects underground conducting materials by transmitting electrical pulses along loops of cables laid on the ground surface. It is an inductive method, which utilizes a strong direct current passed through a square loop commonly extended on the ground surface. The flow of this current in the surface loop creates a primary magnetic field, which spreads out into the ground. When the applied current is abruptly terminated, the primary magnetic field starts to decay with time. According to Faraday’s law, the decay of the primary magnetic field with time induces eddy currents that flow outward and downward in the subsurface conductors. The rate of change of these currents and of their respective secondary magnetic field depends on the size, shape and conductivity of the subsurface conductors.

Ground Penetrating Radar (GPR)

It is an electromagnetic technique used for high-resolution detection, mapping and imaging of the subsurface soils and rock conditions. It investigates the subsurface conditions by transmitting radio waves into the ground and recording the response at the ground surface. This system has a capability to investigate the subsurface medium at different depth levels according the used antenna. Each antenna is designed to operate over a range of frequencies. The high frequency is related to shallow investigations and the low frequency is corresponding to deeper investigations. It is strongly used for Archaeological Investigations.

Very Low Frequency Technique

VLF method utilizes Very Low Frequency radio communication signals in the range of 15-30 KHz, to determine electrical properties of near surface soils and shallow bedrock. The technique is valuable especially for mapping steeply dipping structures such as faults, fracture zones and areas of mineralization.
