Short summary
This paper outlines the results from laboratory tests of soil freezing impacts on infiltration rates, hydraulic conductivity, and soil pore distribution characteristics. The results indicated that macropores (> 5 mm) accounted for < 1 % of the pore-volume-contributed half of the flow in unfrozen conditions and that the freezing of macropores resulted in considerable decreases in hydraulic conductivity. The results should be of interest for cold region hydrology in general.
