Rivers of different basins #006

All this leads to the fact that most of the thawed spring waters do not flow down the surface, but are absorbed into the soil. In the fields, the soil freezes deeper in winter than under the canopy of the forest. With the rapid melting of snow, it does not have time to thaw. Meltwater flows through the frozen ground quickly, without saturating the soil, into valleys and gullies. Spring flooding in forested areas is characterized by a gradual increase in river levels and a longer duration than in treeless areas. In the forest area, most of the precipitation is absorbed into the ground and saturates groundwater, and in treeless areas it flows down the surface. Summer rains in the steppe are often torrential. Rivers violently carry rainwater flowing down from the fields. Therefore, in forest areas, all other things being equal, the climate of the river receives more groundwater supply. The zanders and terraces of rivers are characterized by the most abundant groundwater lying close to the surface. They are characterized by significant, sometimes continuous afforestation. Along with this, the sands, having high moisture capacity and low capillarity, greatly reduce evaporation. In the steppe zone with a negative moisture balance, groundwater supply due to precipitation is unfavorable. Groundwater is on average deeper than in the forest area, and swamps, even in the forest-steppe zone, are rare. On the contrary, as we move towards the southeast of the Russian Plain, the salinity of the soils increases. Groundwater is drawn by salt marshes to the soil surface and partially evaporates. The water content of rivers is also largely subordinated to structural conditions. Rivers whose sources are located within positive geological structures, especially those whose surface layers are composed of Cretaceous and Paleogene rocks with their rich aquifers, receive more constant nutrition. The relief corrects the effect of climate on nature. This effect affects, first of all, the increase in precipitation over the hills and on the slopes of the western exposure. The absence of summer rains and poor groundwater supply in the south-east of the Russian Plain leads to a reduction and even cessation of runoff. This is especially pronounced in the Syrt region of the Low Volga region. Dense syrtic clays and loams, composing the area from the surface, do not allow surface water to pass through. Rivers do not receive groundwater supply and, with the exception of Bol. Irgiza, they turn into chains of lakes in summer, and in dry years they completely dry up. Thus, abundant water supply is typical for the rivers of the basins of the Baltic and northern Seas and the upper reaches of the rivers of the southern direction.
