Description :
In 3 West Siberian geomorphological regions, the snowpack was measured and the soil frost depth, the volume of surface runoff, the humus content of the soil, and the chemical composition of meltwater were determined for each year from 1969 to 2007. The study was carried out on chernozem-type soils during different hydrological years. The water content of the snow varied. Both the amount of snow and the type of land use influence the surface runoff volume. Slopes covered with perennial grasses and plowland had the greatest snowmelt runoff values. The removal of clay particles depletes the humus from chernozem and phaeozem soils. Results and discussion about : the content of exchangeable cations in eroded soils; and the chemical composition of snowmelt runoff and the removal of elements during different hydrological years in West Siberia.
