    abstract = {Eight vertical electrical sounding data sets were obtained 
  from various parts of the study area, located within latitudes 5°05''N and 
  5°37''N and longitudes 7°00''E and 7°30''E in the middle Imo River 
  Basin. The litho-stratigraphic unit of Benin formation was investigated. The 
  sounding data were analyzed with the RESIST Software to delineate the sub-surface 
  layering. The concept of Da-Zarrouk parameters (transverse unit resistance and 
  longitudinal conductance in porous media) was used to determine aquifer hydraulic 
  characteristics. The following values of hydraulic conductivity and transmissivity 
  were obtained for the Benin formation, K<SUB>mean</SUB> = 23.07 m day<SUP>-1</SUP>; 
  T<SUB>mean</SUB> = 704.72 m<SUP>2</SUP> day<SUP>-1</SUP>; K<SUB>max</SUB> = 
  46.97 m day<SUP>-1</SUP>; T<SUB>max</SUB> = 2036.21 m<SUP>2</SUP> day<SUP>-1</SUP>; 
  K<SUB>min</SUB> = 7.02 m day<SUP>-1</SUP>; T<SUB>min</SUB> = 87.05 m<SUP>2</SUP> 
  day<SUP>-1</SUP>. It was established from the study that thick productive aquifers 
  are located in the Benin formation.}
