Abstract

Estimation of hydrodynamic parameters of aquifer is one of the important problems of groundwater resources management. There are many different approaches to estimate the hydrodynamic parameters of aquifer and among them the application of geoelectrical surveys is the most developed one. In this contest forty four vertical electrical soundings have been used to evaluate the hydraulic properties of aquifer in Golgir plain, Khuzestan. The thickness, lateral extent and resistivity of the aquifer layers were determined by the electrical survey and borehole logs. Transmissivity values were inferred using the empirical relationship between hydraulic conductivity and formation factor with correlation coefficient of 0.75. Results show highly variable thickness of the main aquifer in the study area. High values of transmissivity, specific yield obtained in eastern plain part is due to exist erosional course sediment from Asmari limestone formation. Also, Lower average values of porosity were estimated in eastern parts. Finally, geological and hydraulic parameters maps of Golgir aquifer have been produced. Overall results indicate useful estimation of Hydraulic parameters that was used by geoelectric method and they can be used in making decision and future drilling program in the study area.
