Abstract: Studies of snowmelt water infiltration into frozen soils are relatively scarce. There is no simple and clear answer on how water infiltrates into frozen soil. Despite the large amount of empirical studies and modeling attempts, the full process of infiltration in frozen soil is not completely understood. Snowmelt water infiltration involves complex processes of heat and mass transfer through the frozen soils. Many factors, such as soil moisture, soil temperature, water release rate from the snow cover, energy content of infiltrating water, porosity, soil cracks, and presence or absence of macropores, affect the total infiltration process.The research project will focus on snowmelt infiltration characteristics into frozen soil. The specific objectives of the research study are to measure infiltration amount/rate into frozen soil at field and laboratory conditions, to develop a snowmelt water infiltration model based on historic, laboratory and field data, and to evaluate model outputs with other available infiltration models.
