Abstract

The primary factor influencing flow within recharge or discharge wells and groundwater dispersion is the soil hydraulic conductivity. Studying hydraulic conductivity and its variation is a basic condition for the understanding and modeling of flow and contaminant transport processes. Hydraulic conductivity is permitting water seepage through connected voids. Actually, determining the hydraulic conductivity, whether in laboratory or field experiments is sensitive and difficult. Accurate determination of  the hydraulic conductivity still needs more studies. The main objective of this research is to present an experimental study for determining the hydraulic conductivity of porous media as a governing parameter which plays acritical role in studying groundwater flow through an in-depth exploration of soil hydraulic properties. To determine it, a specialized hydraulic model was devised based on the conventional Darcy's experiment. Experimental runs were carried out and measurements were determined. The validity of the device was confirmed and the results were approved and validated by making a comparison with standard values.
