Popis: | An assessment of the current hydrological changes in the Don River basin, the largest river in Russia located in the forest-steppe and steppe zones, is given on the basis of the geographic-hydrological method. Particular attention is paid to identifying the hydrological role of economic activity in catchments on the background of ongoing climatic changes. The contribution of flow from various lands to the spring surface slope runoff was determined. The anthropogenic and climatic changes of the surface slope runoff and infiltration into the soil on arable lands, as well as river runoff, its surface and underground components are calculated. It was found that due to the increase in air temperature, a significant reduction in the river runoff surface component and an increase in its underground component has become a characteristic feature of the river flow formation. It is shown that hydrological changes in the Don River basin have ambiguous after effects and along with negative there are also take place positive consequences. The identified hydrological changes are of a sustainable nature, and it is advisable to take them into account when predicting the state of water resources in the near future. |
