DESCRIPTION
Solapur-Electrical Resistivity Method (ERM) is used for knowing sub surface rock characteristics so as to locate favourable place to drill for underground water. The data acquired can also be used for civil engineering foundation study. We can know sub surface geology with more accuracy & this can be used as an alternative to conventional method of foundation study either or as a complimentary scientific approach that in all help to reduce time & cost of investigation of foundation.
