The final result or product of a geophysical method is to clearly illustrate the geological structure, along an investigation axis (2D profile) or a search area (3D). This means that the specific physicochemical properties of the lithologies and their thickness must be identified, in order to convert the physical dimension of the problem in geological criteria.
Seismic methods: Seismic tomography, mapping fault zones and bedrock, correlation of seismic velocities-elastic constants-density and geotechnical indices in geotechnical research, geotechnical soil characterization. Seismic method in boreholes: Techniques, application and examples in engineering. Applications and examples; Resistivity methods: Electrical resistivity tomography, mapping fault zones and bedrock, mapping polluted areas and industrial pollution, determination of water-saturated zones, landslides, locating fractures and caves, investigation and evaluation of aquifer zones, mapping of industrial pollution, subsurface water flow adumbration.
