Primena modela razmene količine kretanja za procenu krive protoka u koritu za veliku vodu prirodnog vodotoka / Application of the exchange discharge model for the estimation of the rating curve in the compound channel – a case study
(Univerzitet u Beogradu – Građevinski fakultet, 2018)
U svetu se već dvadeset pet godina razmatraju mogućnosti za poboljšanje procene krive protoka u slučajevima kada se voda izlije iz glavnog korita na plavne površine. Razlog za to je činjenica da su ispitivanja u laboratorijskim ...
Numerical Simulation of 3D Flow at Right-angled Confuence with and without Upstream Planform Curvature
(Chemical Industry Press, Beijing, 2010)
This paper aims at studying the effect of upstream planform curvature on the flow in the confluence hydrodynamics zone. To do this, a 3D numerical model is used for simulation of flow at right-angled
confluences with ...
Regulation and Utilization of Flood Water of Karst Polje - Example of Gatačko polje, Eastern Herzegovina
(University of Belgrade, Faculty of Mining and Geology, Center for Karst HydrogeologyHydro-Energy Power Plant "Dabar", Trebinje, 2018)
In general, karst is known as extreme environment for construction of large structures. The average precipitation of karst poljes at Dinaric region of the Eastern Herzegovina for a wet year is about 2450 mm. Daily precipitation ...
Management of Multipurpose Water Storage Reservoir in Flood Water Regimes
(Macedonian Committee on Large Dams, 2017)
As a consequence of climate changes the extreme hydrological phenomena occures, in terms of spatial and temporal variability. In such conditions – of more frequent and extreme high water regimes and reduction of low water ...
Flow measurement at the short structures in hydraulic complex conditions: HE 'Djerdap 2' case study / Merenje protoka na kratkim objektima u hidraulički neregularnim uslovima na primeru HE 'Đerdap 2'
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Hydraulic conditions at short structures in most cases prevents the existence of cross sections with parallel streamlines and fully developed turbulent flow profile. In such conditions the flow measurement is rather ...
Merenje protoka vode u tunelima pri kombinovanim uslovima tečenja: primer tunela Dabarsko Polje - Fatničko polje
(Srpsko društvo za hidraulička istraživanja i Srpsko društvo za hidrologiju, 2018)
U opštem slučaju, metode za merenje protoka vode se mogu klasifikovati prema uslovima tečenja na mernom mestu, pa se tako određene metode koriste u sistemima pod pritiskom dok nešto drugačije u sistemima gde se javlja ...
Multicriteria optimization of natural and recycled aggregate concrete for structural use
(Elsevier Ltd, 2015)
Recycling of concrete waste to produce recycled concrete aggregates (RCA) and its use in the production of structural concrete is the way towards reducing the depletion of natural mineral resources and the amount of ...
Methods for water management and area management in the zone of systems vulnerable to floods: The case study of mine and thermal power plant Gacko / Razvoj metoda za upravljanje vodama i uređenje teritorije u zoni sistema osetljivih na poplave - na primeru rudnika i termoelektrane Gacko
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
Large systems as mines with open pits and thermal power plants are particularly sensitive to flooding. Outage of such systems (due to flooding of mines or threats to other vital elements of the system) cause serious ...
Different approach for calculation of inflow on storm water sewer pumping station: Case study KCS Nova 1 on New Belgrade / Mogućnosti za proračun protoka na kišnoj kanalizacionoj crpnoj stanici - primer KCS Nova 1, Novi Beograd
(Savez inženjera i tehničara Srbije, Beograd, 2012)
In the process of making mathematical models, a common problem is lack or missing data that could be used for calibration and verification of the model. In that case, we have to somehow use available data to calculate the ...
Nonparametic estimation of density functions in hydrology / Neparametarske funkcije raspodele u hidrologiji
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
As an alternative procedure for parametric methods in statistical analysis, non-parametric methods are emerging mainly because of their flexibility and ability to completely automate the estimation of probability density ...
