- Abstract:
-
The infiltration of snowmelt water into ground, one of the most important parts and symbols of hydrologic cycle in frigid zone, is crucial to the researches on generation and confluence process of spring runoff, agricultural irrigation and groundwater simulation and management in frigid zone. It can be reduced to 4 phases: infiltration in snow cover; infiltration in soil melting layer; infiltration in soil frost layer; and infiltration in unfrozen aeration zone. Influencing factors of snowmelt water infiltration into ground can be classified into 3 types. The first are interfaces which include the snow surface, ground surface, upper bound of frost layer, below bound of frost layer and water table. The second include the situation, scale, structure, lithology characteristics, water capacity, water retention and water permeability of the 4 layers above the last are surroundings and regional factors which can also influence the process to some degree.
