20.500.12556/DiRROS-17824 Ocena količinskega stanja podzemnih voda za Načrt upravljanja voda 2022–2027 (NUV III) Groundwater quantitative status assessment for River Basin Management Plan 2022–2027 (RBMP III) Ocena količinskega stanja podzemnih voda je del Načrta upravljanja voda 2022–2027 (NUV III). Z njo po določenih kriterijih ovrednotimo količinsko stanje na 21 vodnih telesih podzemnih voda v Sloveniji kot »dobro« ali »slabo«. Ocena je izvedena s štirimi preizkusi, kjer analiziramo vpliv odvzemov (črpanih količin) podzemne vode na: količine podzemne vode in vodno bilanco, ekološko stanje površinskih vodnih teles, kopenske ekosisteme odvisne od podzemne vode in vdore slane vode ali vode slabše kakovosti v vodonosnik. Končno skupno oceno, na podlagi opravljenih preizkusov, določa kriterij najslabše ocene. Na podlagi rezultatov izvedenih preizkusov imamo 20 vodnih teles ocenjenih s skupno oceno »dobro«. Vodno telo Dravska kotlina pa je ocenjeno kot »slabo«, ker črpanje podzemne vode povzroča vdore vode slabše kakovosti v vodonosnik. Zadnja obdobna ocena količinskega stanja 1991–2020 razkriva, da imamo v plitvih vodonosnikih podzemnih vodnih teles letno na razpolago dobrih 4 milijarde m3 podzemne vode. Odvzemi podzemne vode (črpane količine) so v obdobju 2014–2019 v plitvih vodonosnikih dosegali povprečno 135 milijonov m3/leto. Na območju globokega geotermalnega vodonosnika v Murski kotlini so odvzemi v tem obdobju ocenjeni na 2,5 milijona m3/leto. Numerični modeli simulirajo omejeno napajanje, ki se kaže kot izcejanje iz okoliških kamnin v geotermalni vodonosnik v višini približno 2,3 milijona m3 termalne vode na leto. The Groundwater quantitative status assessment is part of River Basin Management Plan 2022–2027 (RBMP III) and is used to evaluate, according to certain criteria, the 21 groundwater bodies (GWBs) in Slovenia. GWB can achieve good or poor quantitative status. The assessment is carried out with four tests, where the impact of groundwater abstraction (pumped quantities) on: groundwater quantity and water balance, the ecological status of associated surface water bodies, groundwater dependent terrestrial ecosystems and the intrusion of saline or poor water quality into the aquifer is analyzed. The final overall assessment of each groundwater body, based on the completed tests, is determined by the criterion of the worst test assessment. Based on the results of the tests, within the assessment period, 20 GWBs in Slovenia achieved good quantitative status. GWB Dravska kotlina achieved poor quantitative status, because the pumping of groundwater causes poor quality water intrusions into the deeper aquifer of that groundwater body. Within the last assessment period 1991–2020, approx. 4 billion m3 of groundwater was available annually in shallow aquifers within groundwater bodies. Groundwater abstraction (pumper quantities) in the period 2014–2019 reached an average of 135 million m3. In the area of deep geothermal aquifers of the Mura basin, abstractions were estimated to sum up to 2.5 million m3 per year. Latest numerical simulations point out induced aquifer recharge of approx. 2.3 million m3 of thermal water. podzemna voda vodno telo preizkus količinskega stanja vodna bilanca ekosistemi odvzemi groundwater water body quantitative status test water balance ecosystems abstractions true false true Slovenski jezik Angleški jezik Neznano 2024-01-16 09:59:14 2024-01-16 09:59:14 2024-01-17 03:40:22 0000-00-00 00:00:00 2023 0 0 str. 257-273 no. 2 vol. 66 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-12-21 556.3 0016-7789 10.5474/geologija.2023.012 179267075 1865-Article_Text-12342491-1-10-20231221.pdf 1865-Article_Text-12342491-1-10-20231221.pdf 1 C357C6F896ECBC9B54BE68D1ED2EF7AA 9b27275689ca44d4f03d69f017f5f9960e71d644cb6ed56949b735c831bf5bd6 feb30565-b44d-11ee-b0d4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24185 Geološki zavod Slovenije Geologija 0 0 0
