ABSTRACT

The groundwater potential and aquifer vulnerability of Southern Delta University and the surrounding area in the Niger Delta region of Nigeria were investigated using the VES geophysical technique. Additionally, 2D resistivity survey and 1D (VES) soundings were obtained in the field using the Schlumberger and Wenner profiles, respectively. Sixteen (16) VESs point were selected using a Schlumberger array applied for the conduction of the VES. The ABEM Terrameter SAS 1000 was used for this study with maximum current electrode spacing (AB/2) was 150 m. The evaluation of aquifer protective capacity was based on the following Dar- Zarrouk parameters: longitudinal conductance (S), Transverse Unit Resistance (Tr), Transverse Resistivity (𝜌𝑡) and longitudinal resistance (ρL). The aforementioned results ranges from 0.029733 to7.327213, 0 to20135092 Ω/m², 0.00 to 42768.57and 60.695 to 9535.021 Ω-m respectively. Hydraulic conductivity and transmissivity, for example, range from 29.49481 to 1E+165 m/day with an average value of 6.4E+163 m/day, whereas K ranges from 0 to 3.9E+167 m2/day with an average value of 2.4E+166 m2/day. The contour maps help to define zones with distinct layer characteristics by revealing the distributions of these parameters. The results of the study can be used to guide decisions regarding groundwater abstraction and management.
