20.500.12556/RUL-136343 Integrated water quality management model for the rural transboundary river basin—a case study of the Sutla/Sotla River The intensive use of soil and water resources results in a disbalance between the environmental and economic objectives of the river basin. The water quality management model supports good water status, especially downstream of dams and reservoirs, as in the case of the Sutla/Sotla river basin. This research aims to develop a new, improved integrated water quality management model of rural transboundary basins to achieve environmental objectives and protection of the Natura 2000 sites. The model uses river basin pressure analysis to assess the effects of climate and hydrological extreme impacts, and a programme of basic and supplementary measures. The impact assessment of BASE MODEL, PAST, and FUTURE scenarios was modelled using the soil and water assessment tool (SWAT) based on land use, climate and hydrological data, climate change, presence or lack of a reservoir, and municipal wastewater and agriculture measures. Eight future climate change scenarios were obtained with optimistic (RCP4.5) and pessimistic (RCP8.5) forecasts for two periods (2020–2050 and 2070–2100), both with and without a reservoir. The model shows that the most significant impacts on the waterbody come from the nutrients and sediment hotspots, also shows the risk of not achieving good water status, and water eutrophication risk. The modelled average annual increase in sediment is from 4 to 25% and in total N from 1 to 8%, while the change in total P is from −5 to 6%. The conducted analysis provides a base for the selection of tailor-made measures from the catalogue of the supplementary measures that will be outlined in future research. environmental objectives WFD integrated water quality management model good water status rural transboundary river basin Sutla/Sotla climate change scenarios SWAT measures vodni menedžment kakovost voda vodotoki Sotla SWAT model hidrologija true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-25 12:50:48 2022-04-25 12:50:49 2022-09-15 04:13:46 0000-00-00 00:00:00 2021 0 0 27 str. iss. 18, art. 2569 Vol. 13 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 556 2073-4441 10.3390/w13182569 77608707 water-13-02569-v2.pdf water-13-02569-v2.pdf 1 86B3FFCF83756EFB9BF2B5B1399211B7 ee880894f8e056abf4ab64b1bcd0e8c51303082266e56cda3526ad488c110473 d039f7aa-c485-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155935 https://www.mdpi.com/2073-4441/13/18/2569 1 7edb58e5-c485-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155933 Biotehniška fakulteta 0 0 0
