Monitoring vlažnosti zemljišta korišćenjem jeftinih senzora
(Department of Civil Engineering and Geodesy, Faculty of Technical Sciences, University of Novi Sad, 2023)
Vlažnost zemljišta je jedan od važnijih parametara u modeliranju i analizi podzemnih
voda, poljoprivredi, ekologiji i sl. Monitoring vlažnosti omogućava upravljanje vodnovazdušnim režimom zemljišta čime se obezbjeđuju ...
Long-term change in hydroclimatic regimes in catchments across Serbia
(Faculty of Geography, Lomonosov Moscow State University, 2023)
This study presents trend analyses in several catchments across Serbia. The trend analyses are preformed over series of precipitation, temperature and streamflows. These variables are represented by different indicators, ...
Fizički zasnovano modeliranje infiltracije kod prirodom inspirisanih rešenja
(Univerzitet u Beogradu – Građevinski fakultet, 2021)
Prirodom inspirisana rešenja za cilj imaju unapređivanje kvaliteta života u urbanim sredinama pospešivanjem biodiverziteta. Mnoga od ovih rešenja, kao što su zeleni krovovi i biofiltri, su takođe zanimljiva u pogledu ...
Značaj monitoringa kvaliteta vode u jezerima hidroelektrana / The Significance of Monitoring of Water Quality in Hydropower Lakes
(Savez energetičara, 2021)
Pri planiranju akumulacionih hidroelektrana, važan segment je i adekvatan monitoring kvaliteta vode. Uz odgovarajući monitoring program omogućava se višenamensko korišćenje veštačkih jezera. Eutrofikacija vode u jezeru je ...
Procena merne nesigurnosti pri merenju protoka profilisanjem polja brzina
(Društvo Metrologa, 2022)
Za potrebe pouzdanije procene hidrauličke efikasnosti cevnih agregata na HE Đerdap 2, kao i unapređenja efikasnosti nakon revitalizacije agregata, projektovan je i primenjen inovativni sistem za posredno merenje protoka ...
Water retention and transfer properties of a Green roof volcanic substrate
(E3S Web of Conferences, 2020)
The water retention curve and the hydraulic conductivity function of a volcanic coarse granular material used as a substrate in an urban green roof in the Paris area was carried out on a newly developed device, in which ...
Mogućnosti primene DeNSE metode za sektorizaciju distributivnih mreža za redukciju gubitaka
(Savez inženjera i tehničara Srbije, 2023)
Sektorizacija odnosno podela vodovodne mreže na osnovne zone bilansiranja (eng. District Meter Areas – DMAs) predstavlja najisplativiju i opšte prihvaćenu strategiju za kontrolu vodnog bilansa, pritisaka i smanjenje gubitaka ...
A new approach of accounting for impedance effects in Gardner’s method of determining the hydraulic conductivity of unsaturated soils
(E3S Web of Conferences, 2020)
Based on tests carried out on a specific device allowing to determine the water retention and transport properties of granular media at low suctions, an alternative approach to Kunze and Kirkham’s method of accounting for ...
Flow measurement methodology for low head and short intake bulb turbines - Iron Gate 2 case
(International group for hydraulic efficiency measurement (IGHEM), 2022)
Flow measurement of low head turbines, with short intakes like bulb turbines is challenging since there is no “regular” cross-section with fully developed velocity profile. In most situations the flow data during field ...
Uncertainty assessment of flow measurements at Iron Gate 2
(International group for hydraulic efficiency measurement (IGHEM), 2022)
To allow for the reliable hydraulic efficiency estimation of the tubular turbines before and after their revitalization at the Hydro Power Plant (HPP) Iron Gate 2, a novel flow measurement system was designed and tested ...
