DETERMINING AQUIFER TRANSMISSIVITY AND HYDRAULIC CONDUCTIVITY IN KWALE, DELTA STATE, NIGERIA, VIA INTEGRATED ELECTRICAL RESISTIVITY AND PUMP TEST DATA ANALYSIS

The integration of Vertical Electrical Soundings (VES) and pump test analysis has successfully determined the aquifer transmissivity and hydraulic conductivity in Kwale, Delta State, Nigeria. The VES data provided a detailed view of subsurface resistivity variations, identifying potential aquifer zones and layers with reduced permeability. Complementary pump test results confirmed these findings, showcasing the aquifer’s ability to sustain a stable water yield suitable for industrial and domestic purposes. Notably, data from VES 16 near the pump test site highlight localized aquifer property variations, likely influenced by lithological differences. This study delivers crucial insights for groundwater resource management, offering a valuable framework to support water supply planning and sustainable land use in the region.
