A detailed analysis of river flow long-term changes in the Southern taiga subzone of Western Siberia has been carried out with the Chaya River basin as an example. Causal statistical analysis of changes in groundwater levels, bog water level, air temperature and atmospheric precipitation has been performed. The conducted studies revealed a statistically significant trend in the increase of surface runoff in the winter low flow of the Chaya River and its large tributaries (the Iksa and the Parbig), as well as the underground runoff component for virtually the entire year. An ambiguous regularity has been observed in the change of the level regime of rivers. The main reason for the observed changes in the water regime of the said territory is the redistribution of atmospheric moisture and shifting of the boundaries of hydrological seasons.

Plantains produced 5,650, 25,550, 37,800 and 32,260 kg/ha when the water table of a Mollisol was maintained at depths of 12, 24, 36 and 48 cm, respectively. Roots in the upper 15 cm of soil were not affected by depth of the water table. Lowering the water table from 12 to 48 cm increased roots at the 15 to 30 cm depth from 232 to 646 cm/1,000 cm3 of soil, and at the 30 to 45 cm depth from 92 to 498 cm/1,000 cm3of soil.
