Earth Electric Resistivity Meter now part of Civil engineering department
Earth Electric Resistivity Meter instrument added in Civil Engineering Laboratories.Representative from IGIS pvt Ltd Hyderabad came to Civil Engg Department DBATU Lonere for Installation and Demonstration on 2nd November 2020.He explained Installation Process,Working Principles ,Field Demonstration,Post Processing of Data of Resistivity meter to Faculties present in department and Student representatives as Prathmesh Ghuge and Omkar Shinde.
(b) Multi-conductor electrode cables and computer-driven, automated switching, as well as innovative processing of large resistivity data sets, have allowed simultaneous performance of profiling and sounding to produce two-dimensional “electrical images”
Principle
The electrical resistivity method is an active geophysical technique. It employs an artificial source which is introduced into the ground though a pair of electrodes. The procedure involves measurement of potential difference between other two electrodes in the vicinity of current flow. Apparent resistivity is calculated by using the potential difference for the interpretation. These electrodes by which current is introduced into the ground are called Current electrodes and electrodes between which the potential difference is measured are called Potential electrodes.
Applications
1) Ground Water Exploration
2) Bedrock Investigation
3) Delineation of Geological Structures
4) Sand and Gravel Deposit Identification
5) Mineral Investigations
6)Geophysical Field Training
