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 ...
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 ...
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 ...
Technical and Environmental Aspects of Infrastructure Restoration after Destruction of Bridges in the City of Novi Sad
(International Conference on Environmental Recovery of Yugoslavia – ENRY2001, 2001)
This paper deals with the riverbed morphological and environmental changes induced by destruction of bridges in the city of Novi Sad. Different aspects of infrastructure restoration are discussed. The problem of gas pipeline ...
Sewer system management in extraordinary events
(Risk Management of Water Supply and Sanitation Systems, 2009)
This paper deals with the problem of sewer system management in extraordinary conditions - by which are included both non-regular and special events. Extreme precipitation, thick layer of snow and its melting, extreme ...
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 ...
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 ...
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 ...
