Methods of investigation
- Multi-electrode geoelectric method:
- 2D and Electrical Resistivity Tomography;
- Electrical Vertical Soundings (SEV);
- I.P. survey in 2D sections;
- Cross-hole tomography.
- Seismic methods:
- refraction;
- seismic surface waves (1D MASW, profile, and 2D MASW, section);
- SIRT method (cross-hole, side-to-side scan of structures like dams);
- vibrational monitoring of ground and structures, HVSR measurements;
- Bore-hole seismic probes (down-hole, cross-hole).
- GPR method:
- multiarray underground GPR scan;
- wide range of antenna frequencies;
- borehole GPR.
- Frequency domain - electromagnetic (FDEM, up to 15000 Hz):
- 2D EM section;
- 3D modeling.
- Magnetotellurics and Audiomagnetotellurics method (MT and AMT):
- 1D MT sounding;
- combined 2D Electrical Resistivity Tomography and 2D AMT section.
