- Аннотация: —The strengthening of anthropogenic pressure on the catchments of small and medium-sized riversof the Central Black Earth region of Russia, associated with significant plowing and an increase in the numberof livestock complexes, contributes to an increase in the concentrations of organic substances and nutrientsin permanent watercourses. At the same time, the sources of their point discharges are absent. This indicatesan increase in diffuse pollution of rivers as a result of erosion-hydrological processes in economicallydeveloped catchment areas. The case of the formation of catastrophic pollution of the upstream reaches ofthe Psel (Psyol) River, which led to the mass death of aquatic organisms at the 25 km section of the river, isdiscussed. It was found that the reason for this is a catastrophic decrease in waterborne oxygen concentrations,caused by a combination of various active water-erosion processes in the plowed catchment area,related to anomalous rainfall, temperature regime, and hydrodynamic characteristics of this section of theriver channel. It is shown that in the absence of measures aimed at soil and water protection on the catchmentsof small rivers of the Central Black Earth regions, in certain weather-climatic conditions, the diffusewater pollution of watercourses may reach a catastrophic level
