Groundwater quantitative status assessment in Slovenia

Abstract

PovzetekV prispevku so podani metodolo{ki pristopi in rezultati prve ocene koli~inskega stanja enaindvajsetih teles podzemnih voda v Sloveniji. Ocena razpolo`ljivosti vodnih koli~in v teh telesih v obdobju od 1990 do 2001 je 1,43 ⋅ 10 9 m 3 /leto oziroma 727,4 m 3 na prebivalca letno. V letu 2002 odvzeta podzemna voda (0,23 ⋅ 10 9 m 3 /leto) je predstavljala 15 odstotkov razpolo`ljivih zalog podzemnih voda v Sloveniji. Za vsa telesa podzemne vode je bilo ocenjeno dobro koli~insko stanje. AbstractThe framework for the integrated water management of the entire EU area has been set, when the European Parliament and Council passed the Directive 2000/60/EC in 2000. According to the directive, the evaluation of meeting the environmental objectives is based also upon the assessment of quantitative and chemical status of individual groundwater body.The assessment of quantitative status of groundwater bodies under the Groundwater Directive of EU is based on the definition of the available groundwater quantity. This is a long period mean annual renewable quantity of water in the groundwater body, reduced by the quantity of the long period annual groundwater discharge, which is required for sustaining ecological objectives concerning surface water bodies and preservation of the ecosistems, connected with the groundwater bodies.Methodological approach and the results of the first groundwater quantitive status assessment for 21 groundwater bodies in Slovenia are given in this paper. The assessment of the available groundwater quantity in Slovenian groundwater bodies in the period from Ocenjevanje doseganja okoljskih ciljev po tej direktivi sloni na ugotavljanju tudi koli~in-skega stanja po posameznih telesih podzemne vode, ki ga dolo~amo kot razpolo`ljivo koli~ino podzemne vode. To je obdobna srednja letna obnovljiva koli~ina vode v telesu podzemne vode, zmanj{ana za koli~ino ob-

Model-based assessment of groundwater recharge in Slovenia

“…In this framework, the Slovenian Environmental Agency prepares annual reports on the groundwater quantity status which include the groundwater recharge rates for all 21 Slovenian groundwater bodies quantified with the distributed GROWA model (Andjelov et al 2006;Uhan et al 2010;Uhan 2012). On the regional level, GROWA model results are used for the sustainable development of transboundary groundwater bodies, e.g.…”

“…The same is true for further implementation of the European Water Framework Directive (EU WFD 2000) and the Groundwater Directive (EU GWD 2006). Up to now, only lumped information about groundwater recharge rates in Slovenia is available for all 21 groundwater bodies (Official Gazette of Republic of Slovenia 65/2003Slovenia 65/ , 63/2005Andjelov et al 2006).…”

Groundwater quantitative status assessment for River Basin Management Plan 2015-2021 in Slovenia

“…Prvi poskus delne ocene količinskega stanja podzemnih voda v Sloveniji, ki je sledil zahtevam nove okvirne direktive o vodah, je bil leta 2006 izveden na Agenciji RS za okolje (ARSO) s podatki državnega hidrološkega monitoringa površinskih in podzemnih voda desetletnega obdobja ob koncu preteklega stoletja (andJeLov et al, 2006;, ter kasneje razširjen z upoštevanjem procesov celotnega hidrološkega cikla in rezultatov modeliranja napajanja vodonosnikov oz. količinskega obnavljanja podzemne vode v Sloveniji (andJeLov, 2009;uhan, 2010).…”

The three-dimensional regional geological model of the Mura-Zala Basin, northeastern Slovenia

“…The lithostratigraphy of the Mura-Zala Basin was first interpreted for purposes of oil and gas research in the 1950s-1960s (PleničaR, 1954;ciGit, 1958;vončina, 1966), which was followed by a geological mapping for the Basic Geological Map of Yugoslavia (PleničaR, 1968;Mioč & ŽnidaRčič, 1978, 1998aničić & JuRiša, 1984;ŽnidaRčič & Mioč, 1987;MaRKović & Mioč, 1988). The determination of Miocene formations was based on lithological, biostratigraphical and geophysical markers (naftaPlin, 1966;GRandić et al, 1986;tuRK, 1993;Mioč & ŽnidaRčič, 1996).…”

“…The youngest sediments are mostly gravelly alluvial deposits of the Drava and Mura rivers. They are of Quaternary age and an important drinking water resource (andJelov et al, 2006).…”
