Hydrological and climatic conditions of water resources formation in the South of Western Siberia

Hydrological and climatic features of the formation of water resources in any territory are closely related to the conditions of formation of incoming elements of water and heat balance. The use of the method of hydrological and climatic calculations (GCR) developed by V. S. Mezentsev and tested in most regions of Siberia and adjacent territories involves the determination of flow characteristics by the equations of water and heat energy elements. In the presence of indicators of values of total moisture and heat and power resources of climate, these equations allow calculating values of actually all components of balance equations, both for a year and an intra-annual interval. The application of the GCR method in determining the elements of the water balance in the conditions of flat areas, which include the South of Western Siberia, allows obtaining runoff characteristics with satisfactory accuracy. The paper identifies the features of formation and distribution of elements of water and heat balance in the study area, determines their values for the territory of Western Siberia and checks the calculated values of flow by comparison with the measured ones.
