20.500.12556/RUL-178708 River water quality of major rivers in Slovenia in the context of climate change Kakovost vode večjih rek v Sloveniji v kontekstu podnebnih sprememb Climate change affects surface water quality parameters, including river quality. This study analyses changes in climate parameters, specifically air temperature and solar radiation, and their impact on river water temperature. It also examines how changes in river water temperature and organic matter load affect oxygen saturation levels, a key indicator of river water quality. Using water quality data, the status as well as temporal and spatial trends of the analysed parameters were assessed for the period between 2007 and 2024 on the three largest Slovenian rivers: the Drava, Mura, and Sava. Relative importance analysis of temperature and biochemical oxygen demand (BOD) using the Random Forest machine learning method showed that water temperature in the analysed rivers has an impact ranging from 51% to 66% on predicting oxygen saturation. The selected approach to analysing watercourse quality parameters enables the assessment of the impact of these parameters on river water quality. Based on these results, it will be possible to implement appropriate measures promptly to achieve sustainable river management by establishing a strategy that, under climate change conditions, safeguards water quality and maintains ecosystem protection, ensuring long-term ecological and socio-economic benefits. climate change water temperature biochemical oxygen demand (BOD) oxygen saturation river water quality statistical analysis R software sustainable river management Slovenia podnebne spremembe temperatura vode biokemijska potreba po kisiku BPK nasičenost s kisikom kakovost rečne vode statistična analiza programska oprema R trajnostno upravljanje rek Slovenija true false true Angleški jezik Slovenski jezik Članek v reviji 2026-01-29 17:15:35 2026-01-29 17:15:44 2026-02-02 09:40:55 0000-00-00 00:00:00 2026 0 0 19 str. iss. 3, [article no.] 1338 Vol. 18 Jan. 2026 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 502/504:556.5(497.4) 2071-1050 10.3390/su18031338 266707715 sustainability-18-01338_(1)_(1).pdf sustainability-18-01338_(1)_(1).pdf 1 0D261E989072AD1285D0F3A2DAE88FAB e60f0bb0672a6379b5b7a557035038a4bf3bdac8531f7985d3408e2c587ba5a7 1253dc12-fd2e-11f0-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=226687 https://www.mdpi.com/2071-1050/18/3/1338 1 bb510036-fd2d-11f0-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=226686 Fakulteta za gradbeništvo in geodezijo 0 0 0
