“…While, at the river upper reaches, the width of the riverbed is 2-7 m, within the precincts of the city of Belgorod, the river width amounts to 6-10 m with a depth of 1.0-1.5 m; in the areas subjected to dredging, however, the width reached 20-40 m with a depth of up to 6 m. Now, the riverbed of the Vezelka River, at a length of >4 km, represents a cascade of technogenic reservoirs, considerably slowing down the water exchange rate in the river and partly fulfilling the function of the accumulation of urban sewage (rainwater). An investigation of the modern transformation of the floodplain type of the locality [63] has shown that, as a result of the reduction in the length of the riverbeds for the period of 1964-2008, the reconstruction of the localities took place, as well as the replacement of the floodplain type for the post-floodplain case. On the former floodplain meadows, there are now areas of multi-storey and residential buildings and social, business, and recreational zones.…”

“…This is why the phenomenon of the degradation of small rivers can be observed everywhere, since the latter cannot cope with the movement of all sediments formed on the watershed area. Earlier, an important conclusion was made [63] that the decrease in the volume of spring flood runoff, which is characteristic of the rivers in the European part of Russia, acts as a factor in the dynamics of the water richness of small rivers and, at the same time, as a factor in their degradation in the upper reaches.…”

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.

“…Повышение температуры приземного слоя атмосферы, которое характерно для всей территории России [6], вносит существенные изменения в ход природных процессов. Подтверждением этому являются рассмотренные примеры, а также авторские исследования других составляющих гидрологического режима рек Донского бассейна, в частности, термического [7].…”

Рассмотрена изменчивость атмосферных осадков по сезонам года, на основании которой делается предположение, что осадки не являются главной причиной особенностей водного режима и снижения максимального стока. В качестве доминирующего фактора современных изменений высоты половодий выступает состояние подстилающей поверхности, а именно, глубина промерзания и осеннее увлажнение почвы, которые на фоне повышения температуры воздуха регулируют снеготаяние, насыщение почвы водой и образование склонового и речного стока. Глубина промерзания почвы син-фазна величине максимального стока.
