- Аннотация: Extreme low flow on rivers (when water flow was less than or equal to the value of75 and 90% exceedance probability), observed in years with severe meteorological andagricultural droughts in the Russian Plain (1972, 1975, 1981, 1995, 1998, 1999, and 2010)were studied. In 1972 and 1975, the exceptional low flow was recorded in the largest area,including the basins of the largest rivers (the Volga, Don, and Dnieper) and even the outlet, aswell as in their tributaries. One of the heaviest droughts (2010) accompanied the abnormallylow flow only in the Lower Volga and its tributaries in the eastern part of its basin. In otheryears with severe meteorological and agricultural droughts, their occurrence areas in theRussian Plain were much less. In 1975, extreme low flow was recorded in the rivers of theVolga, Don, and Dnieper basins in the main hydrological seasons (during summer–autumnlow-water season and snow-melt flood), as well as all the year round, including their outlet (intheir lower reaches in the general case and in the middle reaches in the case of the Dnieper).However, in these seasons in 1972, extreme low flow was recorded in rivers in the basins ofthe Don and Dnieper (while in the Volga, it took place only during summer–autumn low-waterseason), and in 2010, it formed only in the Volga basin. Abnormally low flow in years withsevere droughts were recorded mostly in rivers of the forest–steppe and steppe zones, as wellas the southern part of the forest zone.
