The unfrozen water content can include free water that can be moved by gravity, and/or interfacial (adsorbed) water that cannot be moved by gravity. The main factors controlling the unfrozen water content in frozen ground (or in partially frozen ground) are temperature, specific surface area of mineral particles, mineral type, pore size distribution, dissolved-solids content of the pore water, and kind of exchangeable ions. The unfrozen water content at temperatures below 0°C is highest in clays and decreases with decreasing temperature, clay content, and dissolved-solids content, and with increasing particle size. Unfrozen water content, like total water content, can be determined either gravimetrically or volumetrically.
