20.500.12556/RUL-134718 Impact of land use on karst water resources a case study of the Kupa (Kolpa) transboundary river catchment This paper presents a qualitative approach for assessing land-use pressures on the water resources of a transboundary Dinaric karst catchment of the Kupa River in Southeast Europe. Spatial analyses of the water quality indices for surface water and groundwater were carried out in a GIS environment, as well as a detailed assessment of man-made hazards based on recommendations of COST Action 620. The produced maps provide an insight into the qualitative status of water resources at a regional scale by indicating areas of potential negative impacts of land use through the identification of point and diffuse sources of pollution. Higher values of the water quality indices for surface water and groundwater are observed in lowland areas, karst plateaus and poljes, where the impacts of anthropogenic activities such as agriculture and quarries take place on karstified permeable carbonate rocks. Hazard assessment showed how transport infrastructure induces a low hazard level. Settlement areas without proper sewerage systems impose moderate hazard levels, while direct wastewater discharges into groundwater and waste illegally disposed in karst swallow holes and caves located near settlements were classified as having high hazard levels. The applied methods proved to be suitable even in challenging karst environments where the complex properties and structure make the exploration and monitoring of groundwater resources difficult and scarce. water quality index hazard assessment COST Action 620 water resources land use Kupa (Kolpa) River catchment karst hydrogeology CAMARO-D project true false true Angleški jezik Ni določen Članek v reviji 2022-01-27 13:20:40 2022-01-27 13:20:41 2022-09-14 04:09:31 0000-00-00 00:00:00 2020 0 0 21 str. iss. 11, art. 3226 Vol. 12 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 55 2073-4441 10.3390/w12113226 38136579 RAZ_Selak_Ana_2020.pdf RAZ_Selak_Ana_2020.pdf 1 B7344364397661793033BA0555A8A5F5 c213e62f8cb6bcb1bda9b4d0ed022ff61a8f4d2540869dcfa338a19c3a80e805 e314907a-7f6b-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153317 https://www.mdpi.com/2073-4441/12/11/3226 0 74e2da61-7f6b-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153316 Naravoslovnotehniška fakulteta 0 0 0
