“…Finally, mention should be made that the above-mentioned hydrological (a reduction in spring snowmelt-induced discharge) and sheet/rill/gully erosion intensity changes (a decrease in annual river load/yield) in the basins of the main studied plain rivers of the Ciscaucasia (the Kalaus River and the Kuma River), in river basins of the central part of the northern slope of the Greater Caucasus (the upper Terek River basin) and possibly the lowland part of the Kuban River basin, were similar in their common features to those previously described in many regions of the neighboring East European Plain [13][14][15][16][17][19][20][21]23,25,[27][28][29]71,73,83,84], in the Baltic countries (Estonia, Latvia, and Lithuania) [85], as well as in Eastern Scandinavia [86], Poland, Belarus, and in the north of Ukraine [87]. That is, it was a sizeable regional phenomenon for Eastern and Central Europe.…”

“…For instance, tendencies towards a decrease in the intensity of sheet/rill/gully erosion processes, the accumulation of their products, and also a reduction in river sediment load/concentration have been found over the last decades in many administrative regions and river basins of the forest-steppe and steppe zones of European Russia characterized by a relatively high degree of agricultural development. All of this was possible by using various approaches and methods, such as modeling [17,18], analysis of hydrological (suspended sediment load) data [19][20][21], stationary studies [22], field and remote monitoring [23][24][25], field research based on a variety of chronomarkers [26][27][28][29], and so on. Despite these and other numerous results, many of European Russia's regions are still "blank spots" regarding this field of research.…”

Contemporary Long-Term Trends in Water Discharge, Suspended Sediment Load, and Erosion Intensity in River Basins of the North Caucasus Region, SW Russia

For the first time, contemporary trends in water discharge, suspended sediment load, and the intensity of overall erosion in the river basins of the North Caucasus region, as one of Russia’s most agriculturally developed geographic areas, were identified. The study was carried out using monitoring data of the Federal Service for Hydrometeorology and Environmental Monitoring of the country for 21 rivers by comparing two periods: 1963–1980 and 2008–2017. According to the study’s results, trends of an increase in the mean annual water discharge (by 2–97%) and the essential reduction in its intra-annual variability have been found in most of the studied rivers. On the contrary, the trends of reduction in annual suspended sediment load and the intensity of erosion in the river basins were identified in most of the study region. Their most essential and statistically significant decreases (by 47–94%) were recorded within the Stavropol Upland, which several decades ago was considered one of the most erosion-dangerous territories of the entire country, as well as in some river basins of the central part of the Greater Caucasus’s northern slope (by 17–94%). The changes in climate (reducing the depth of soil freezing and meltwater runoff on the soil) and land use/cover (reduction of acreage and load (pressure) of agricultural machinery on the soil, reducing livestock on pastures, and the transfer of water from the neighboring, more full-flowing rivers) are considered the leading causes of the aforementioned trends. The findings will contribute to solving some economic and environmental problems of both the region and adjacent territories and water areas.

“…Therefore, if during 1963-1986 the average rates of dry-valley bottom sedimentation of washed-out soil material, using radiocesium as a chronomarker for sediment dating, were 0.92-1.81 cm per annum, then during 1987-2015 they were only 0.17-0.50 cm per annum, i.e., they reduced by at least 72-81%. It is noteworthy that in this part of the Republic of Tatarstan, where the basins of these rivers are located, almost 60% of the studied gullies almost completely stopped linear growth from 1960-1970 to 2009-2016 [77].…”

Contemporary trends in cultivated land and their influence on soil/gully erosion and river suspended sediment load were analyzed by various landscape zones within the most populated and agriculturally developed part of European Russia, covering 2,222,390 km2. Based on official statistics from the Russian Federation and the former Soviet Union, this study showed that after the collapse of the Soviet Union in 1991, there was a steady downward trend in cultivated land throughout the study region. From 1970–1987 to 2005–2017, the region lost about 39% of its croplands. Moreover, the most significant relative reduction in cultivated land was noted in the forest zone (south taiga, mixed and broadleaf forests) and the dry steppes and the semi-desert of the Caspian Lowland—about 53% and 65%, respectively. These territories are with climatically risky agriculture and less fertile soils. There was also a widespread reduction in agricultural machinery on croplands and livestock on pastures of the region. A decrease in soil/gully erosion rates over the past decades was also revealed based on state hydrological monitoring data on river suspended sediment load as one of the indicators of the temporal variability of erosion intensity in river basins and the published results of some field research in various parts of the studied landscape zones. The most significant reduction in the intensity of erosion and the load of river suspended sediment was found in European Russia’s forest-steppe zone. This was presumably due to a favorable combination of the above changes in land cover/use and climate change.

“…Verkhneuslonsky municipal district of the Republic of Tatarstan (map-scheme) shows fragments of a map of the expositions and slopes of the relief of the Verkhneuslonsky district. The watershed faces the Volga valley with high steep slopes with angles of up to 65 degrees[7]. The plakar surfaces and the water surface of the Kuibyshev reservoir correspond to zero slope values.…”

GIS-technology and data of earth remote sensing to identify and predict ravine erosion development

et al. 2020

View full text Add to dashboard Cite

This article discusses the study of the process of ravine erosion using geoinformation technologies and Earth remote sensing data. Ravine erosion, which develops on the territory of the Verkhneuslonsky municipal region of the Republic of Tatarstan, is considered as a multifactorial process. The possibility of using freely available data to study the factors affecting ravine erosion is evaluated. It is shown that in modern conditions of increased anthropogenic environmental impact, especially in areas heavily divided by ravines, the use of GIS technology is sufficient in order to monitor and quickly respond to negative erosion processes occurring on agricultural lands.
