TECHNOLOGIES FOR RESTORING THE QUALITY OF SURFACE WATERS OF THE SMALL RIVER TYNNIVSKA WITHIN THE TERRITORY OF RIVNE

Abstract

The article calculates the level of anthropogenic load on theTynnivska river basin, which indicates that its landscape as a whole ischaracterized as unstable with a pronounced instability. Acomprehensive assessment of the ecological status of the TynnivskaRiver Basin shows that under the influence of growing anthropogenesis and climate change the river basin has undergone significantchanges, which has led to riverbed diversion, floodplain development,changes in river hydrology, reduced water flow and significant surfacedeterioration. Assessment of the quality of surface waters of the riveraccording to Ie indicators showed that the most polluted is the thirdsection of the river, where critical levels of pollution of the river hydroecosystem are recorded. The quality of water along the entire lengthof the river in terms of nutrients varies from III to V class, in terms ofanthropogenic load – from good status to the crisis of the aquaticecosystem. In the first and second sections of the river the surfacewater quality belongs to the 3rd class – good condition, according tothe level of anthropogenic load – ecosystem shaking, in the thirdsection of the river the water quality belongs to the 5th class – systemcrisis. According to the level of anthropogenic load, the Tynnivskariver basin should be divided into three sections. Hydrotechnicalmeasures are recommended to be carried out within the areas thatwere identified based on engineering and environmental studies and analysis of the level of anthropogenic load on the river basin, namely:in the first section – optimization and rational use of structuralelements of the river basin, organizational – economic measures,clearing riverbeds, construction of bioplateau; in the second section –construction of a bioplateau according to the type of surface flow,construction of a supporting culvert from box gabions filled withzeolite; on the third section, it is recommended to visit a cascade ofbioplateau at the warehouse of a rose site, a site for additionalcleaning on the bioplateau because of the long-term growth.
