Abstract

Vipavska dolina je svojevrstna pokrajina v jugozahodni Sloveniji. Poleg površinskih voda so, čeprav očem skrite, pomembne tudi podzemne vode. Prispevek predstavlja analizo gladin podzemne vode v piezometrih v Vipavski dolini. Analiza je bila izvedena na 10 piezometrih, ki delujejo še danes, in obsega prikaz nivogramov in osnovnih statistik, korelacij, vpliva oddaljenosti od struge reke Vipave, trendov in sezonskosti. Glede na višino kot gladin podzemne vode lahko piezometre v Vipavski dolini razdelimo v tri skupine. V prvo skupino z najvišjimi kotami spadajo piezometri Gradišče, Vipavski Križ in Ajdovščina, v drugo skupino piezometri Prvačina, Šempeter, Volčja Draga, Renče in Vrtojba, v tretjo skupino pa piezometra z najnižjimi kotami Miren in Orehovlje. Rezultati analiz so pokazali, da med gladinami podzemne vode v posameznih piezometrih ter med gladinami podzemne vode in gladino reke Vipave na različnih vodomernih postajah obstajajo boljše ali slabše povezave. Nihanje gladine podzemne vode je pogojeno z oddaljenostjo od struge reke Vipave in z geološko oziroma tektonsko zgradbo območja. Enoznačnega trenda gladin podzemne vode ni mogoče določiti. Sezonskost nihanja gladin podzemne vode ni izrazita, se pa najvišje vrednosti pojavljajo v jesenskem in zimskem času, najnižje pa v poletnem.

Secondary title: Analysis of groundwater levels in piezometers in the Vipava Valley
Secondary abstract: The Vipava Valley is a unique region in south-western Slovenia. In addition to surface water, groundwater is also important, although it is hidden from the eye. The paper presents an analysis of groundwater levels in piezometers in the Vipava Valley. The analysis was performed on 10 piezometers, which are still operating today, and includes a display of levels and basic statistics, correlations, the impact of distance from the Vipava riverbed, trends, and seasonality. According to the groundwater level, piezometers in the Vipava Valley can be divided into three groups. The first group with the highest levels includes piezometers Gradišče, Vipavski Križ, and Ajdovščina, the second group piezometers Prvačina, Šempeter, Volčja Draga, Renče, and Vrtojba, and the third group with the lowest groundwater levels includes the piezometers Miren and Orehovlje. The results of the analyses showed good or bad connections between groundwater levels in piezometers, as well as between groundwater levels and the Vipava River water level at various gauging stations. The fluctuation of the groundwater level is conditioned by the distance from the Vipava riverbed and the area’s geological or tectonic structure. An unambiguous trend of groundwater levels cannot be determined. The seasonality of groundwater level fluctuations is not pronounced, but the highest values of groundwater levels occur in autumn and winter, and the lowest in summer.
