S. Makarenko popup.description2  Theoretical and methodical aspects of geographical, hydrological and geoecological analysis of the zivers and river basins of the area (its essence, scientific approaches, principles, basic notes) have been presented. The appropriate conception and algorithmic model of geoecological analysis of regional rivers, including its phased blocks: 1) the geographical and hydrological analysis of regional rivers; 2) the estimation of results of object and subject relations between the society and natural water bodies; 3) the ways for efficient water consumption justification and the improvement of hydroecological situation for regional rivers optimisation have been worked out. The conditions for river flow formation (natural and anthropogenic) have been analysed, unfavourable natural processes, caused by constant water flow and aggravated by man’s activities, have been detected. The peculiarities of hydrological characteristics and hydrological regime of rivers in Sumy region have been defined. Hierarchical structure of hydrological regional systems have been determined and described, three levels of landscape and hydrological differentiation have been distinguished – zonal, provincial and district, reflecting the main features of hydrological Sumy region area organization, as a result the landscape and hydrological zoning has been executed. The rate of anthropogenic pressure on basin of regional rivers has been defined.8 river basins were called to be under moderate anthropogenic pressure, 27 river basins – under medium and 26 basins undergo high level of anthropogenic pressure, but 5basins are characterized with very high level of anthropogenic pressure. The quality of river water according to the water contamination index has been estimated – the water of regional rivers is characterized as “pure”, “moderately contaminated” and “contaminated” and according ecological evaluation for water quality. The later proves that according to the final integral index (ІЕ) the te Product Description popup.authors Danilchenko Olena S. popup.nrat_date 2021-05-14 Close
