Climate change is one of the most discussed topics around the world. They occur both globally and regionally and are not synchronous in time and space. This research is devoted to analysing climatic changes in the basin of the Sea of Azov. The territory is located in the south of the European part of Russia and includes the basins of the Don and Kuban rivers. The reference stations are in different landscape zones: forest-steppe, moderate-arid steppe, arid steppe, dry steppe, semi-desert. The study period is 1961-...

This paper analyzes the changes of trends in temperature and precipitation in the Azov sea basin. The nature of this territory has undergone major changes. It is an important agricultural and industrial area. The paper considers changes in temperature and precipitation at stations located mainly in the steppe zone. Maximum, minimum, mean air temperature and precipitation trends on a seasonal and annual time scale are evaluated from data recorded at twelve weather stations in the basin of Azov sea during the period...

Climate change and its impact on the environment is an urgent problem of the present time, causing hydrological changes and ecosystem change. As a result, formed ecosystem representing less valuable in economic terms, low productivity. Therefore, study of climate change is an important and urgent task. Global climate changes in the South part of Russia is reflected in the warming of the winter period and an increase in the amount of precipitation during the cold season. This paper analyzes the changes in meteorolo...

One of the main contaminants in groundwater of South Russia is nitrate and being one of the essential problems of water providing system needs a solution. It was in 1981 when World Organization of Health pointed on necessity nitrate studying soil and water. Estimation of nitrate contamination in groundwater, used in housekeeping, of Rostov region was held. Results give an opportunity to find out and estimate tendency of changing quantity of contaminant in groundwater and can be regarded as foundation for further e...

Springs are one of the essential part of water suppling system in Rostov on Don. Nearly 60 springs are known to exist in the city. Rostov region is located in the arid climate zone, where there are limited natural resources of fresh groundwater. At the same time, region due to the regional hydrogeological relation is situated at the junction of four artesian basins in their regional parts focused significant resources of fresh pressure water. Springs and wells in Rostov on Don are pumped from the Azov-Kuban aquife...

East Donbass is one of the oldest coal mining area of South Russia. The most significant change of surface and groundwater water quality. This study is devoted to the investigation of chemical properties of surface waters. The main source of the contamination of surface and groundwater are industrial and domestic wastewaters, drainage and mine waters. Surface waters within the region have high mineralization and water hardness. Water in springs and wells is unsuitable for potable use due to high salinity and hardn...
