Geophysical Resistivity Meter Geophysical Survey Equipment Geophysical Equipment Price Ground Water Detector and Ground Water Detection Equipment
The geophysical equipment can be used in energy exploration and civil geophysical prospecting, railway and bridge survey, mental and non-mental mineral survey. It can also be used in hydro- and engineering geology survey, such as underground water, water reservoir dam site, flood control dam hidden trouble detection, and geothermic field survey.
Among all geophysical methods, resistivity methods are most widely used in ground water, mineral and oil
exploration. The multi electrode electrical resistivity imaging (ERI) play a very significant role in the resistivity/IP
prospecting, for detecting sub-surface formations and for studying sub-surface geological stratal architecture.
Electrical Resistivity imaging (ERI) survey is carried out at two identified locations of Cauvery plains viz.,
kottuchery and kadalangudi. The site selection is done on the basis of local geology, geomorphology etc. The
resistivity images with Dipole-Dipole at kadalangudi location showed up to 22 m depth whereas Wenner Schlumberger, the scanned depth is 60m. Thus the resistivity image with Wenner-Schlumberger arrays has shown greater depth of investigation. Also it is observed that high resistivity layer is almost embedded between two low resistivity formations.
