Groundwater investigations In The Enugu Area Using Electrical Resistivity Methods

Electrizal resistivity Investigations were
conducted on the kjali Sandstone at 9th Mile Corner
(Enugu Ngwo) of the Anambra sedimentary basin. The
project was geared towards coctributing to the solution
of the groundwater problems of the area. The vertical
and horizontal variations of resistivity were determined
along several profiles. Most of the vertical electrical sounding curves correspond to five - layer models. Partial curve - matching techniques and the use of
auxiliary point methods were tze approaches employed for
the interpretation of the sounding curves. From the data,
the depth to the acquifer varied between 5Om and SSm,
and subsequent drilling data obtained from boreholes in
the area closely agree with these results.
