Title: Geophysical investigation for groundwater in the Tain district of the Brong Ahafo region of Ghana using the 2D CVES method
Authors: Issah, Mohammed Mansuru
Issue Date: 9-Nov-2015
Abstract: The 2D continuous vertical electrical sounding (2D CVES) surveys using the Wenner configuration were carried out in twenty communities in the Tain District. The objectives are to assess the subsurface geology, identify high groundwater potential zones in each community and the possibility of drilling high-yielding boreholes that could yield sustainable amount of groundwater for hand pump water supply. A total number twenty two 22 profiles were surveyed at least one in each community. The collected resistivity data was converted from the apparent resistivity data to 2D model section using the least-square inversion with the help of Res2Dinv software. The 2D resistivity model-section produced a high quality structural resolution leading to the demarcation of the layering of various lithological units, weathered layers and identification of important structures such as joints, fissures, fractures and faults. These structures are quite substantial in groundwater exploration. The study revealed that the potential water-bearing aquifer in the Tain district in the Black Volta Basin are mostly as a result of weathering of the overburden and fracturing of the underlying bedrock. The results of the study therefore suggest that the hydrogeology of the studied region is highly complex since the development of groundwater is generally due to secondary porosities. Based upon the results of the geophysical investigations, the groundwater potential zones in the twenty two communities were selected and expected to produce sufficiently high yielding boreholes enough for hand pump water supply system.
