Hydraulic model study of turbulent flow measurement in sewer pipes conjunction / Hidraulička modelska ispitivanja merenja protoka na spoju kolektora sa silovitim tečenjem
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
This paper presents capabilities and benefits of use of physical models for flow analysis in large sewer pipes and conjoining objects. A group of objects pertaining to the Belgrade Sewer System is modeled and results are ...
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 ...
Compiled free surface mathematical models uncertainty propagation / Propagacija neodređenosti kod linijskih modela otvorenih tokova
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Free surface flow is usually simulated by 1D numerical models. This approach assumes flow simplification and requires model calibration in order to reproduce flow characteristics in a realistic way. The calibration and ...
Assessment of the position and dimensions of the ski-jump scour-hole / Procena položaja i dimenzija erozione jame ski odskoka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
This paper is concerned with the ski-jump design, mainly for the large overflow dams. Although the vast scope of literature on this subject exists, there is still a need to compile, elaborate and upgrade available knowledge. ...
Field measurement of small velocities / Merenje malih brzina u terenskim uslovima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
The application of 2D and 3D Computational Fluid Dynamics (CFD) modeling in open river flow is gaining in its popularity, especially in the field of sediment deposition on the river confluences and bay entrances. The ...
Ultrasonic flow measurement method: Working principles and use in water distribution and sewer systems / Ultrazvučna merila protoka u sistemima vodovoda i kanalizacije
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
Flow metering in Water Supply and Sewer Systems (WSSS) is the essential need Technical reason are the water balance control and the operational management. In the scope of inevitable privatizations (in Serbian environment) ...
Optimization of water allocation from a multipurpose reservoir / Efekti primene pravila upravljanja pri raspodeli vode iz višenamenske akumulacije
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
The ever increasing water demand in conditions of divergent variability of both natural flows and water requirements can only be met by finding new water sources, combined with the building of new water storage reservoirs. ...
Theory and new applications of structure analyses of daily hydrologic series / Teorijske osnove i proširenje oblasti primene strukturne analize dnevnih hidroloških serija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
Structure of daily hydrologic series, based on TIPS methodology (Yevjevich, 1984), is extended and new possibilities for stochastic analyses and applications are presented. First, estimation of smoothed time functions of ...
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 - ...
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 ...
