One of the important parameters for determining the discharge through the subsurface system in groundwater engineering is hydraulic conductivity coefficient. This parameters the factor of oil skeleton and fluid properties. The horizontal and vertical components of saturated hydraulic conductivity coefficient can be obtained from the laboratory and field testing methods. Those are usually constant and variable head tests. In this research the three-dimensional ellipsoid of hydraulic conductivity coefficients is obtained. Using the hydraulic conductivity ellipsoid it is possible of obtain the permeability of soil in any direction. The above model has the effective application for calculation of one, two and three-dimensional fluid flow in the anisotropic porous media. The accuracy of thehydraulic conductivity obtained by the model can be checked by laboratory tests. The model is applied for the calculation of infiltration from the natural or man-made surface channels, also exfilitration from the subsurface water resources.
