The recent epoch differs from the previous ones in a large set of natural resource management types and inter se in the presence of environmental management systems to transform the landscape sphere. In particular, the article examines the mining complex impact on the structure of natural (landscape; hydro-geological; environmental) resources. The purpose of the work was to analyse the role of the anthropogenic factor in the impact of continental runoff and the change in the chemical quality of the sea shelf waters. During deposits development movable rock masses are dumped into disposal areas while refuse ores accumulating in tailings pits. The new landscape conditions to have been emerged impact on natural aquatic ecosystems. This is manifested in decreased water in the quarries of the Kostomuksha ore cluster, in mixed surface and ground water. A change in the hydrodynamic conditions causes the transformation of hydrochemical composition of river and lake ecosystems; increased content of dissolved chemical components; river bed load to enter the western part of the Arctic seawaters of the main drainage area - the White Sea. Thus, there is a geo-technical system being formed, and it goes beyond the scope of land-use management of the mining enterprise as such and involves ecosystems of various hierarchical levels with diverse energy and material flows. As a result, we have identified and characterized a regional geo-ecological problem to have impacted the entire northern and central parts of Karelia in combination with the adjacent seawater areas.","PeriodicalId":319336,"journal":{"name":"20th International Multidisciplinary Scientific GeoConference Proceedings SGEM 2020, Water Resources.

The object of the study are the maximum water discharges during the spring flood on the Tikhaya Sosna river near the town of Alekseevka (right tributary of the Don river) and Vorskla river near the village of Kozinka (left tributary of the Dnieper river). These rivers were chosen as objects of study due to the fact, that the analysis of the zonal and azonal distribution of runoff over the territory of the Belgorod region allows us to correlate their main characteristics as close in values. The flow dynamics during the flood period for the rivers of the Don and Dnieper basins has a negative trend. The decrease in the river flow of the flood, which is typical for the most part of The Russian plain, occurs mainly under the influence of climatic factors, whose contribution to the decrease in the value of modern runoff is estimated at 80%. The values of the maximum flow rates of the Tykhaya Sosna river and the Vorskla river have pronounced fluctuations over the years depending on meteorological conditions. The main factors influencing them, are: water storage in snow before snowmelt, the intensity of the snowmelt and rainfall period, high water, humidity and the degree of freezing of soils and the presence of an ice crust on the soil surface. Thus, the determining factors affecting the nature of the formation of the maximum costs of the spring flood of the Tikhaya Sosna and Vorskla rivers are the growth of average annual temperatures in the catchment area of these basins. This factor also causes a decrease in the depth of soil freezing. This causes large losses of water for infiltration and leads to a pronounced shortage of river flow.","PeriodicalId":319336,"journal":{"name":"20th International Multidisciplinary Scientific GeoConference Proceedings SGEM 2020, Water Resources.
