Title (croatian) Hidrauličko-hidrološka sinteza hidrograma istjecanja krškog izvora Golubinka Title (english) Hydraulic-hydrology synthesis of Golubinka karst spring discharge hydrograph Title (german) Hydraulisch-hydrologische synthese des ausflusses der karstquelle Golubinka Author Goran Lončar Author Željko Šreng Author Vedran Ivezić Author's institution University of Zagreb Author's institution Josip Juraj Strossmayer University of Osijek Scientific / art field, TECHNICAL SCIENCES Abstract (croatian) Prikazana je hidrauličko-hidrološka analiza i rezultati hidrograma istjecanja za krški
izvor Golubinka, što obuhvaća razdoblje 7. rujna 2012. do 1. listopada 2013. Cilj je bio
stjecanje uvida u procese koji se javljaju na slivnom području izvora Golubinka, u smislu
količine istjecanja, razina podzemne vode i procjeđivanja unutar krškog vodonosnika, u
odnosu na količinu oborina izmjerenih tijekom analiziranog razdoblja. Na osnovi dvaju
pristupa određen je odgovarajući koeficijent turbulentnog procjeđivanja kroz krške kanale
analiziranog vodonosnika koji se potom može koristiti u numeričkom modeliranju.
Abstract (english) The hydraulic-hydrology analysis and discharge hydrograph results for the Golubinka
karst spring are presented for the period from 7 September 2012 to 1 October 2013.
The objective was to gain insight into processes occurring in the Golubinka spring
drainage area, in terms of quantities of discharge, groundwater levels, and seepage
within the karst aquifer, as related to the precipitation measured during the analysed
period. An appropriate coefficient of turbulent seepage through karst channels in
the analysed aquifer was determined based on two approaches. This coefficient can
subsequently be used in numerical modelling.
Abstract (german) Dargestellt werden die hydraulisch-hydrologische Analyse und die Ergebnisse des
Hydrogramms des Ausflusses für die Karstquelle Golubinka, was den Zeitraum vom 7.
September 2012 bis zum 1. Oktober 2013 umfasst. Das Ziel war es, Einblick in die Prozesse
zu erlangen, die im Wassersammelgebiet der Quelle Golubinka im Sinne der Ausflussmenge,
des Grundwasserniveaus und der Filterung innerhalb des Karstgrundwasserleiters
auftreten, im Vergleich zur Niederschlagsmenge, die während des analysierten Zeitraums
gemessen wurde. Aufgrund zweier Ansätze wurde ein entsprechender Koeffizient
der turbulenten Filterung durch die Karstkanäle des analysierten Grundwasserleiters
festgelegt, der dann bei der nummerischen Modellierung angewendet werden kann.
