This research discusses the way of defining hydogeological parameters by using monitored data of the ground water system, for defining the values of these coefficients on large areas, which has a practical significance especially in modeling the hydrogeological problems which allows explaining and checking the hydrodynamic and the hydrogeological structures of the area and the reasons of changing the filteration properties of the aquifer. It appears that transmissivity varied from 36 to 570 m2/day, the permeability from 1 to 53 m/day, and the water yield from low to medium between 0.00004 and 0.2 because of the rising of the coefficient of diffusion. The filtration recharge approximately from 1 - 40% from the rain falls. The obtained results are in good conformity with the geological characteristics - structural and litologic - facies characteristics for the study area.
