The purpose of the study was to determine the hydrologic significance of the soil air flow and of its compressibility in the process of infiltration and moisture redistribution. Results of a numerical solution of the equations describing the simultaneous flow of air and water in a soil are presented. The results show that the air flow and compressibility may affect significantly the infiltration rates and the saturation profiles.
