“…The decrease in the role of erosion during the spring snowmelt period is also confirmed by observations of river runoff. For the forest and forest-steppe zone of the East European Plain [19][20][21], stable trends have been established to reduce the maximum annual water discharge during the spring snowmelt. Over the past 70 years, it has decreased by 2.5-4 times.…”

Among the reasons for soil degradation, runoff-induced erosion causes the greatest damage to agriculture in European Russia. One of the effective tools for regulating soil erosion is changing the structure of sown areas and the composition of crops with a focus on soil conservation and rehabilitation land use. The aim of this paper is to present the results of the impact of the program on river-basin nature management and the adaptive landscape agriculture system (ALAS) on changes in soil losses due to storm erosion in one of the agriculturally most developed and, at the same time, most eroded administrative regions of European Russia—Belgorod Oblast. In this study, the calculation of potential soil washout was carried out for three cropland models: (1) The maximum erosion potential of the territory, expressed in terms of soil washout from bare (clean) fallow areas; (2) soil washout, considering the actual structure of sown areas over the past 10 years; and (3) soil washout, considering the full implementation of projects for the erosion-control organization of cropland within the framework of ALAS. The calculation of erosion-induced soil losses was carried out according to the USLE model adapted to regional environmental conditions, while the C-factor values were set separately for each model. For model 1, the average soil loss is 11.3 t/ha per year; for model 2, it is 3.5 t/ha per year; and for model 3, it is 2.2 t/ha per year. It was found that the current programs for the biologization of agriculture and the contour-reclamation organization of cropland would have a noticeable erosion-control effect. It is noteworthy that the greatest efficiency was modeled for areas with unfavorable relief conditions, with up to 40% reduction in soil losses as compared to actual ones.

“…In the Central Chernozem region of the European part of Russia, which is the focus of this study, significant changes in the water discharge of small rivers have been recorded [61]. This was due to increased economic activity within the watersheds, as well as significant climate change.…”

“…The annual precipitation has been reduced from 605 to 523 mm in the last ten years, compared to the preceding 20-year period, while the annual average air temperature, on the contrary, has risen from +7.7 • C to +8.2 • C, respectively. The considerable changes in the characteristics of the vernal runoff and water discharge during the summer and winter low-water periods observed in recent times suggest that the redistribution of the discharge during the seasons of a hydrological year should be taken into account in the hydrological calculations and prognoses for the assessment of the ecological/environmental conditions of rivers and water reservoirs linked with the latter [61].…”

The basin of the small river studied here (the Vezelka River, Belgorod Oblast of European Russia) is located within an urban area (22% of the basin). This circumstance determines its specificity as an object of synergetic anthropogenic impact. The purpose of the work was to develop and test approaches to the integral assessment of the hydroecological situation both in the watershed and riparian zones based on hydrological, hydrochemical, and hydrobiological data and estimates of soil erosion, river water quality, and the pollution of river bottom sediments. The selection of the Vezelka River and its watershed for the study was due to the presence there of two water intakes for a town with a population of 2439 people per sq. km, repeated bottom deepening in the riverbed, and the fact that there is a single regional small-river hydrological station (although there are 567 rivers < 25 km long in Belgorod Oblast). Analysis for 1951–2021 showed a steady decline in water discharge since 1991; thus, over the past three decades, the discharge has decreased by 2.4 times. The reduction in the length of the river network of the study region by 38% over the past 250 years and the assignment of water (at 10 gauging stations) to 3–4 quality classes (extremely and heavily polluted) indicated the exhaustion of the possibilities for the self-purification of the river water. These estimates for large and medium rivers were clearly confirmed by the investigation of the water in the small river studied. In the summer low-water periods, the maximum allowable concentrations in fishery water bodies were exceeded by 2–10 times in terms of Cu, Fe, ammonium, oil, and biochemical oxygen demand. The reconstruction of the floodplain–channel subsystem of river–valley landscapes was substantiated as the final stage of the concept of basin nature management, replacing the continuous deepening of the channel without proper erosion control measures in the watershed area and the organization of buffer zones along the river banks.
