Changes in runoff and water quality in the catchment areas of the reservoirs

[摘要] According to experimental data, a significant decrease in the surface slope runoff from agricultural land in recent decades in the southern part of the Russian plain, including the Volga basin, as a result of mainly climate change has been shown. Part of the decrease in surface runoff entering rivers and water bodies from agricultural land is offset by increased runoff from urban areas. In general, the diffuse removal of biogens (nitrogen and phosphorus) has decreased, although in many areas it exceeds their flow into rivers and wastewater reservoirs, in particular in the catchment area of small tributaries of the Cheboksary reservoir.
