The object of research is a canal from the city of Bilyayevka to the Turunchuk River and other water objects in the territory of the Bilyayevsky united territorial community. The subject of research are relief of the bottom, morphometric characteristics (length, width, cross-sectional area, depth, water surface area, etc.), flow velocity, water consumption and suspended sediment, turbidity of water, characteristics of bottom sediments (granulometric composition, content of organic substances, thickness of the layer of marble, etc.), physical and chemical indicators of water quality (temperature, transparency, smell, taste, color, pH of water, content in water of dissolved oxygen, ions of calcium, magnesium, sodium, potassium, fluoride ions, chloride ions, sulfate ions, orthophosphate ions, nitrite ions, nitrate ions, ammonium ions, alkalinity of water, total content of impurities, content of dissolved and suspended substances), coefficients and periods of water exchange, water quality. The purpose of the work is to study the current state of the canal and ducts from the city of Bilyayevka to the Turunchuk River and to develop scientifically substantiated recommendations for improving its status in the future. Research methods are hydroecological research (hydrological, hydrochemical, topographic and geodetic and others) on large and small rivers and lakes; chemical analysis of water; assessment of surface water quality according to the relevant categories; calculation of coefficients and periods of water exchange. The following tasks were solved in the work: - measured depths, maps of the relief of the bottom are compiled and the basic morphometric characteristics (length, width, cross-sectional area, average and maximum depth, water surface area, etc.); - measured flow velocities, turbidity of water, water flow and suspended sediment; - selected samples of bottom sediments and defined characteristics of bottom sediments (granulometric composition, content of organic substances, thickness of the layer of marble, etc.); - selected water samples and identified physical and chemical indicators of water quality (temperature, transparency, smell, taste, color, pH of water, content in water of dissolved oxygen, ions of calcium, magnesium, sodium, potassium, fluoride ions, chloride ions, sulfate ions, orthophosphate ions, nitrite ions, nitrate ions, ammonium ions, alkalinity of water, total content of impurities, content of dissolved and suspended substances); - water exchange (coefficients and periods of water exchange) and water quality were estimated; - recommendations for improving the hydroecological state of water objects have been developed (the channel to the Turunchuk River, yerykiv, canals and lakes) in the territory of the Bilyayevsky united territorial community.
