Abstract
The study integrated Remote Sensing and Vertical
electrical sounding techniques in the
delineation of groundwater potential zone in
the study area. It employed Landsat 7 ETM+ imagery of 30m
resolution, topographic and geologic maps of the area. These were analyzed in a
GIS environment to obtain the thematic maps of groundwater indicating factors. furthermore,
Ffifteen VES data were acquired from various points within the study area using
the Schlumberger electrode array, at a maximum spread of AB/2 = 400 and MN/2 =
50 and Ohmega Resistivity meter. The correlations between the results from the two
techniques were used to establish areas of good or otherwise low – moderate
groundwater potentials. The result indicated a resistive region at the uplands and
conductive region at the lowlands. Aquifer resistivity, aquifer thickness and
transverse resistivity were high at Ihechiowa, Umuzumgbo, Ugwuakuma, Eziama,
Ututu, Ameke Abam, while they recorded poor - moderate values at the low lands
of Ndi Okorie, Ndi Okereke, Amuvi and Amanagwu. High storability for aquifers
at the uplands suggesting sustainable aquifer yield to boreholes and good
aquifer potentials in the region were inferred. This study establishes that
fact that the two techniques can be effectively used for groundwater assessment.
