What is a good method to locate underground water for a well?
1 Answer
Resistivity technique
Explanation:
Resistivity is defined as the resistance to current flow as a result of an applied electrical potential. In geophysical surveys resistivity is determined as the electrical resistance per length of a unit cross section area (such as
Resistivity surveys are performed by applying an electrical current across two electrodes into the earth. Measuring the change in voltage across two receiving electrodes provides results.
