This study aims to evaluate the hydraulic characteristics of the unconfined aquifer in the Laylan area, Kirkuk, Iraq. The pumping test was carried out on four wells in the Laylan area. all wells penetrate the quaternary sediment, which consists of sand, gravel and clay, the monitoring of the change in the groundwater table was carried out by the groundwater depth detector and the self-potential device, as the purpose of this study was to find an alternative to the traditional methods that monitor the draw down during pumping test, whose use is often accompanied by many obstacles and especially most of the wells belong privately to the farmers, where the goal was to find a relationship between the self-potential readings and the change of the water depth that measured by groundwater depth detector. a mathematical relationship was obtained that links the values of the two variables. In addition, the conductivity value was calculated by substituting the self-potential value in the equation to find the draw down values and then entering into the aquifer-win program. The geophysical self-potential value is very sensitive to the groundwater level changes the correlation coefficient between each of them as in the wells (pw1, pw2, pw3 ) is 0.95,-0.83 and -0.86 respectively, It is a strong and inverse relationship. Transmissivity values for the wells PW1,PW2,PW3 ,PW4 were 12.32 m2 /day, 17.22 m2/day, 78.29 m2/d (10 m2/d) respectively and the hydraulic conductivity for the wells PW1, PW2, PW3, PW4 were 0.113 m/day, 0.21 m/day, 1.74 m/day, 0.25 m/day respectively the obtained hydraulic conductivity value was an approach to the hydraulic conductivity values obtained in the traditional methods. Therefore, the equation can be used in aquifers if it was in the same conditions as this basin. Therefore, the SP device can be considered a successful alternative to traditional measurement methods.
