Comparison of Soil-Freezing and Soil-Water Characteristic Curves of Two Canadian Soils

The drying–wetting and freezing–thawing cycles significantly influence the soil pore water in the vadose zone in permafrost and seasonally frozen regions. The soil-freezing characteristic curve (SFCC) describes the relationship between unfrozen water content and subzero temperature in a soil at froz...
