Nutrient balance from agricultural pollution sources on selected 1 tributaries to the Švihov reservoir

Popis výsledku v původním jazyce

Agriculture is the leading source of non-point sources of water pollution, especially in terms of the 12 runoff process. Agricultural management promotes extensive water contamination, soil erosion and 13 sedimentation in streams and reservoirs. The water reservoir Švihov on the Želivka river supplies 14 drinking water to more than 1.5 million people. The catchment area of the water supply reservoir is 15 intensively used for agriculture, more than 55% of the catchment area is arable land. Nutrients such as 16 phosphorus and nitrates in the upper water-ways of tributaries are a huge problem. The aim of the 17 research is to evaluate concentration trends and losses of nutrients (nitrates and phosphorus) at the 18 chosen tributaries to the Švihov reservoir during 2018- 2021. From the data on monthly concentrations 19 and monthly discharges the monthly and annual losses of nitrates and phosphorus on each profile were 20 calculated. The effect of discharges and concentrations on the magnitude of losses was investigated by 21 correlation analysis. The influence of the forebay Trnávka dam on the magnitude of nutrient losses was 22 also evaluated. The results show the importance of discharge magnitude on nutrient losses. The Trnávka 23 forebay dam significantly reduces the transport of phosphorus from the Trnava catchment to the Švihov 24 reservoir. In the catchment area of the reservoir it is recommended to implement nature-friendly and 25 technical measures for water retention and accumulation in the landscape in order to reduce nutrient 26 transport.
