Controls at river confluences with discordant beds / Uticajni činioci na rečnim ušćima sa izdignutim dnom pritoke
(Savez građevinskih inženjera Srbije, Beograd, 2012)
The role of four parameters that are controlling river confluence hydrodynamics at discordant beds confluences is investigated using 3D numerical model. These are: the junction angle α, the momentum-flux ratio between the ...
Metodologija određivanja potrebnih količina voda za vodosnabdevanje naselja za potrebe vodoprivrednih analiza
(Srpsko društvo za zaštitu voda, 2020)
U radu je prikazan pregled korišćene terminologije i metoda za određivanje potrošnje i potrebe za vodom iz vodovoda. Ukazano je prisustvo u praksi i literaturi različitih termina i metoda za obračun i prikazivanje ovih ...
Numerical modelling of supercritical flow in circular conduit bends using SPH method
(China Ocean Press, 2017)
The capability of the smoothed-particle hydrodynamics (SPH) method to model supercritical flow in circular pipe bends is considered. The standard SPH method, which makes use of dynamic boundary particles (DBP), ...
Effects of bed material grain-size distribution on bed morphology at a river confluence - numerical study
(EGU (European Geophysical Union), 2017)
River confluences play an important role in the drainage of a catchment and transport of sediments and pollutants within this area. Riverbed morphology at these important nodes of the river drainage network might be very ...
Hydrodynamics of 90o concordant beds’ confluences of straight-channels with unequal channel widths
(EGU (European Geophysical Union), 2017)
With the exception of confluences of large alluvial rivers, tributary channel is usually narrower that the channel of the main-river. hydrodynamics of confluences of equal width channels has been thoroughly studied using ...
Pregled i ocena analitičkih modela ušća / Analytical models of confluences: a survey and models’ assessment
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2011)
Na spojevima otvorenih tokova strujnice postaju zakrivljene, jer vertikalno ubrzanje fluidnih delića nije zanemarljivo u odnosu na ubrzanje zemljine teže, pa su to mesta gde ne važe osnovne pretpostavke na kojima se zasnivaju ...
Flood flow frequency analysis in the presence of outliers / Statistička analiza velikih voda u prisustvu izuzetaka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
Flood flow frequency analysis is performed on the series of hydrological observations. The observations introduce uncertainties in the analysis results, inherited from limited data sets, operational difficulties in high ...
Using CFD and real-magnetic field of EM probes to improve the accuracy of flow measurements in mixed flow conditions
(IAHR Joint Committee on Urban Drainage, 2017)
Flow measurement in mixed flow conditions is a challenging task, which can be performed only by few techniques like ultrasonic and electromagnetic. Usually despite the flowmeter’s special design, the systematic uncertainty ...
Distributed hydrologic model for runoff simulation in karst basin / Razvoj distribuiranog modela za hidrološke simulacije oticaja na slivovima u karstu
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
The hydrological mathematical models for modeling the genesis of runoff in the basin become considerably more complex in terms of the highly karstified basins, in which the dominant component of sinking and flow through ...
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 ...
