On the effect of the bed morphology on the river confluence hydrodynamics
(Proceedings of the International Conference on Fluvial Hydraulics - River Flow 2006, 2006)
A river confluence is known for the strong three-dimensional flow effects. The confluence hydrodynamics is significantly influenced by the river bed morphology. Two morphological features are typical for river confluences: ...
Oblikovanje ulaza u zaliv primenom modela ravanskog i prostornog tečenja / Designing a Bay Entrance With 2D and 3D Numerical Model
(Građevinski fakultet Univerziteta u Beogradu, 2006)
Najveći problem zaliva je zasipanje - prirodan proces koji se ne može izbeći. Visoki troškovi održavanja zaliva (bagerovanja mulja i čišćenja obala) nameću potrebu mera za smanjenje uvlačenja nanosa u zaliv. Budući da je ...
Streamflow measurement by salinity dilution method / Merenje protoka u otvorenim tokovima metodom razblaženja koncentracije soli
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Streamflow measurement often requires a clearly structured measurement reach. Velocity distribution can then be measured using a current meter or by constructing a hydraulic section control (weirs or flumes). However, in ...
Instability analysis of the air-water flow in porous medium / Analiza pojave nestabilnosti kod dvofaznog strujanja u poroznoj sredini
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
The paper deals with modeling of two phase (water-air) flow in coarse porous medium, where, after reaching some air velocity, instability of the flow occurs. Firstly, a linear stability analysis has been conducted for ...
Estimating the capacity of double side-channel spillways / Procena propusne moći dvostrukog bočnog preliva
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
A double side-channel spillway consists of two spillways, with channels joining into a common single branch, noting that for some specific site conditions such arrangements may suit better than the conventional one-side-channel ...
Garantovani ekološki protoka kao ključna mera zaštite voda / Guarantied Ecological Discharge as a Main Water Resources Criterion for Water Protection
(Jugoslovensko društvo za zaštitu vodaDruštvo za zaštitu voda Srbije, 2000)
Izbor garantovanog ekološkog protoka koji se ispušta iz akumulacije jedna je od najvažnijih odluka koja mora da se donese pri planiranju akumulacije. u radu se kritički analiziraju metode za određivanje garantovanog ...
Large Scale Particle Image Velocimetry: Measuring urban runoff / Large Scale Particle Image Velocimetry - merenje urbanog oticaja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
Measuring velocities and discharge in the field is well established hydrologic discipline essential for observing and studying the hydrological processes. Small discharges formed on urban areas during rain events are usually ...
2D modelling of water quality in bays / Modeliranje kvaliteta vode u zalivu primenom modela ravanskog tečenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
Contamination of river waters in terms of scale, intensity, and duration cause such severe problems that application of conventional engineering methods for environmental remediation projects is no longer adequate, and ...
Application of 2D and 3D modelling in bay entrance design / Oblikovanje ulaza u zaliv primenom modela ravanskog i prostornog tečenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
Bays suffer from siltation, which is a natural process that cannot be avoided. The main cause of this process is mixing of the river-water containing suspended sediment and the river-bay water. High costs of maintenance - ...
Numerical simulation of the three-dimensional flow at the confluence of the Sava and Danube Rivers
(Research Publishing Services, 2006)
In this paper, the confluence hydrodynamics at the mouth of the Sava and Danube Rivers in
the city of Belgrade is analysed by means of the three-dimensional numerical model. The
confluence offers excellent possibilities ...
