Hydraulic and Geoelectric relationships of Aquifers Using Vertical Electrical Sounding (VES) in parts of Obudu, Southern Nigeria
Languages of publication
Aquifer geoelectric (Formation factor and Porosity) and hydraulic parameters (Transmissivity and Hydraulic Conductivity) were estimated using VES in parts of Obudu, Southern Nigeria. Hydraulic parameters study would help in to reduce additional expenditures in carrying out pumping tests. Hydraulic parameters are used to estimate the groundwater supply potential, protective capacity rating, soil corrosivity and designation. Most of the estimated aquifers have poor protective capacity rating, low designation, smaller withdrawal for local water supply and slightly corrosive. The objectives of this study is to delineate relationship between geoelectric and hydraulic parameters in the study area, There is a strong correlation between hydraulic conductivity (K) with Porosity and Formation Factor respectively as 0.81 and 1.00, while a weak correlation exist between Transmissivity with Porosity and Formation Factor, respectively as 0.11 and 0.15. The regression equation of the hydraulic parameters and geoelectric parameters from the study area are; , , , , where K; Hydraulic Conductivity, T; Transmissivity, F; Formation Factor and ; Porosity. The range of formation factor, porosity, transmissivity and hydraulic conductivity are 11.80 – 132.50, 8.69% - 29.11%, 1.32 – 19.64 and 0.52 – 0.67 respectively.
