OhmMagic Ver 2.0
Geophysical Underground Imaging Device
Typical applications for the OhmMagic system include:
1- Geotechnical investigations
2- Construction site investigations
3- Borehole to borehole and borehole to surface tomography imaging
4- Fracture and cavity detection in bedrock
5- Groundwater exploration
6- Environmental investigation (i.e., mapping of pollution plumes, etc.)
7- Investigation of dam leakage
8- Sand and gravel exploration
9- Site characterization for development
10- Site investigation for horizontal drilling
11- Site investigation for tunneling operation
12- Archeological studies.
The DC resistivity imaging method is especially valuable in areas where ground penetrating radar (GPR) and EM methods do not work because of conductive overburden. Conductive materials, for example clay, attenuates the radar (EM) signal so that no result, or very limited result, can be achieved. In such areas, which are very common in large areas of the world, the resistivity method is the only real alternative for subsurface 2D and 3D mapping of the near surface.
Field procedure is simple. First set out electrode stakes at even intervals. Then lay out the electrode cable and attach each take-out to the stakes. Finally connect the OhmMagic instrument to the electrode cable, perform an automatic test to check that everything is connected correctly and then start the automatic recording. The resistivity measurements are stored directly in the memory of the instrument. When the field measurement is complete, inverted from apparent resistivity into "true" resistivity and presented as a color cross-section of the subsurface.
