Calculating the Geoelectrical Parameters of Selected Wells in Al-Ishaqi District - Salah Al-Din Governorate/Central Iraq
The current study aims to calculate the geoelectrical parameters of the confined aquifer saturated with water, which is located within the sediments of the Quaternary period in the southwestern part of Salah al-Din. It is in the Balad district in which coefficients are represented by the values of longitudinal conduction (T), whose values are 0.18-0.55. The transverse specific resistance (RT) and its values are 3207- 7603, the longitudinal (volume) resistance (rb) and its values 87-157, and specific cross-sectional resistance with its values 86-155, while the asymmetry coefficient (FF) whose values are 26-51. Also, some statistical relationships of hydrogeophysical coefficients were calculated and contour maps were drawn with the values of these operators in the study area
