Hydrogéophysique
The hydrogeophysic is the study of the subterranean water flows (Hydrogéologie) by methods Géophysique S.
The principal methods geophysics are:
- the electric survey: study of the underground electrical resistance in a point
- electric tomography of resistivity: profile of electrical resistance of the basement by assembly of electric surveys.
- electromagnetism: study of the conductivity of the basement by inducing an electric current there.
- the study of spontaneous and caused polarization
- protonic magnetic resonance: study of the electromagnetic signal emitted by the protons (H+) present in the water of the basement.
