摘要：The aim of the study was to characterize hydraulic parameters controlling groundwater occurrence in Kabatini aquifer of Lake Nakuru Basin, Kenya. The study utilized a combination of resistivity sounding and pumping test data. Vertical Electrical Soundings (VES) were carriedout at close vicinity of eight drill sites, to relate geoelectric and hydraulic parameters. Resistivity data were analyzed using EarthImager1D to obtain layer parameters within the constraints of lithology. This study has modified available petrophysical/pore-scale network relations and the bond shrinkage models so as to obtain a basis for applying geoelectrical methods in hydraulic parameter estimation. The adjustment has resulted intoacalibratedfieldscalehypotheticalcomparisonbetweentransmissivity,Tandapparent formation resistivity factor, Fa. A linear relationship (lnT=.0.584lnFa+2.054; with correlation 82.9% percent), with a negative gradient between natural logarithm of transmissivity and apparent formation resistivity factor has been observed. The gradient of which is dependent on the bond shrinkage factor, x (0
