“…Socio-economic development depends majorly on water considering its importance on plants, animals and human activities such as agricultural industry, manufacturing industry, transportation industry, construction industry, home usage and life which cannot be overemphasized (1) , (2) . The abundance and value of groundwater resources transcends from generation to generation.…”

Aim/objectives: This research is geared towards integrating Vertical Electrical Soundings (VES) and Electrical Resistivity Tomography (ERT) profiles constrained with geoelectric sections and borehole logs to assess the vulnerability of the aquifer units employing Aquifer Vulnerability Indexing (AVI) method. Method: The dataset used in this study comprises of fifty VES, five ERT profiles surveyed in parts of Enugu north in Enugu state, two geoelectric sections and three borehole logs. The computer and manual interpretation of VES resistivity data using WinResist software gave values of resistivity, depth and thickness of each geoelectric layer using half current electrode spacing of 1.0 to 450.0 m and maximum current electrode spacing of 900 m. 2D imaging data from the measured field resistance values were processed using RES2DINV×32 version 3.71.115 software. The geoelectrical sections show the variation of resistivities with depth along transcent lines. The geohydraulic parameters were also estimated. Finding: Interpreted VES data revealed five to six geoelectric layers and fundamental parameters generated were used to estimate the values of hydraulic conductivity (σ) and hydraulic resistance (C) of the covering layers ranging from 0.010 to 0.769 mday −1 and 40.47 to 8292.0 day −1 respectively. This research revealed high hydraulic conductivity in the western part implying good groundwater potential with moderate to high protective capacity while areas with low hydraulic conductivity correspond to areas with high resistivity indicating little or no pore space and total devoid of water. The hydraulic resistance quantifies groundwater vulnerability using AVI and reveals that the area of study is characterized by low to high AVI with moderate AVI dominanting. Originality and novelty: The estimated geohydraulic properties from resistivity data and their spatial spread are promising and could increase the depth of knowledge on groundwater vulnerability within and around the study area.

“…Since hydraulic conductivity is controlled by the intergranular porosity and fracturing, the low values of K in the southern parts may be attributed to poor communication channels in the pore spaces and the variation in grain size. According to literatures, the movement of groundwater contaminants is controlled by hydraulic conductivity (Chandra 2008;Obianwu et al 2011;Ibanga & George 2016;Ibuot et al 2017;Obiora et al 2018).…”

“…The disadvantages of using the pumping test to determine the geohydrodynamic parameters have been overcome by the use of an indirect geophysical method (electrical resistivity technique) to estimate the parameters, and these parameters are known to correlate well with the parameters from pumping tests in boreholes (George et al 2017a;Ibuot et al 2019). Electrical resistivity method has been proven useful in characterizing the subsurface aquifer pore properties and the mechanism of electrical conduction through the subsurface (Soupios et al 2007;Khalil & Monterio Santos 2009;Ibuot et al 2013;George et al 2015;Obiora et al 2018). The electrical resistivity data aids in generating information that are useful in delineating the aquifer repositories and its distribution (Mbonu et al 1991;Riddell et al 2010;Ibuot et al 2013;Andrade 2014;Alhassan et al 2015).…”

This study employs the surface geoelectrical resistivity method to investigate the aquifer repositories by estimating the geohydrodynamic parameters; aquifer quality index (AQI), flow zone indicator (FZI), permeability, hydraulic conductivity, fractional porosity, formation factor, normalized porosity index, and tortuosity. The data were obtained from vertical electrical sounding (VES) employing Schlumberger electrode configuration across seventeen locations within the study area. The interpretation of the field data was done using computer software package known as the WINRESIST and the results gave the values of resistivity, depth and thickness of each geoelectric layer at each VES point. The values of aquifer resistivity and thickness were used to estimate the geohydrodynamic parameters, and their variation trends are shown in the contour maps. It was delineated that high permeability zone have high porosity, AQI, FZI, and hydraulic conductivity but low formation factor and tortuosity. This is a reflection of high pore connectivity and groundwater transmissibility in the aquifer repositories. The various plots illustrate the interrelationship between the parameters and gave unique information which could be employed in groundwater contamination modeling, management and abstraction.
