CLIMATOGENIC CHANGES IN THE RIVER AND UNDERGROUND RIVER FLOW OF THE ORSHA ARTESIAN BASIN
Abstract
The article presents longterm changes in the flow rates of the rivers of the Orsha Artesian basin, it is shown that the main factors influencing the conditions of flow formation are primarily climatic, geomorphological and hydrologicalhydrogeological conditions of the region. On the territory of the Orsha Artesian basin, a statistically significant decrease in runoff during the spring flood and a decrease in its share in the annual runoff were revealed (the power of the negative trend ranged from 5.4 to 22.0 %). A significant increase in the share of winter runoff in the annual distribution for the rivers of the Orsha Artesian basin was revealed. As a result of constructing twofactor regression models of the relationship between winter expenditures and spring flood water expenditures, it was found that an increase in the share of winter river runoff is associated with an increase in the air temperature of the cold months, with an increase in the frequency of thaws, and the passage of winter floods. The results obtained indicate that the underground runoff in the winter has increased, due to mild winters, the presence of frequent thaws and sufficient humidification of the territory .
