It is really important to choose correct geophysical method to achieve the project objective. Geophysical methods or techniques are designed to exploit one or more of the physical properties of a target feature that is in contrast with its host environment.
Choose Geophysical Methods Correctly
Inappropriate geophysical methods can lead to failure in detecting or image the targets. Therefore, understanding which methods are suitable for what we want to find are really important.
Schematic diagram below shows summary of geophysical methods with appropriate geological and hydro-geological targets.
Resistivity Survey
Resistivity or Electrical Resistivity survey is best used in hydro-geological studies such as groundwater exploration. But, it also suitable in mapping bedrock or structure, cavities and ground variations.Seismic Survey
Seismic survey can be refraction, reflection or S-wave (surface wave) seismic. These technique are the best to reveal the geotechnical properties and mapped bedrock profile or structure.However, they can be used in hydro-geological studies.
