Electrical resistivity survey for groundwater investigations

DUK-2A Resistivity Tomography System were purchased in 2015

WDDS-2 VES equipment (resistivity meter) can automatically measure and memorize voltage, current, apparent resistivity, and SP parameter. It is widely used in the hydrological and engineering survey, such as ground water seeking; dam base evaluation and flood control dam incipient fault and so on

Electrical resistivity tomography (ERT) or electrical resistivity imaging (ERI) is a geophysical technique for imaging sub-surface structures from electrical resistivity measurements made at the surface, or by electrodes in one or more boreholes. Electrical Resistivity Tomography (ERT) is an advance

The resistivity of homogeneous, isotropic ground that would give the same voltage-current relationship as measured.
