Numerical simulation of concentrated release of dredged sediments into the river / Numerička simulacija koncentrisanog ispuštanja izbagerovanog nanosa u maticu reke
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
This paper deals with prediction of hydraulic consequences of concentrated release of dredged sediments into the river using a two-dimensional numerical model. It is shown that flow, concentration, and siltation fields can ...
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 - ...
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 ...
Roller compacted concrete in dam construction part two: Mixture proportioning and properties of RCC / Primena valjanog betona u izgradnji brana II deo - komponente i osobine valjanog betona
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2003)
This paper deals with properties off cement, fly ash, aggregate and admixtures as ingredients of RCC. Mixture proportioning methods are analyzed particularly The Method of proportioning RCC to meet specified limits of ...
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 ...
Dynamical monitoring of deformation structures in real time / Dinamičko praćenje deformacionih struktura u realnom vremenu
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2004)
Deformation of structures are results of the various processes. Measurements techniques which used today give more opportunities for good processes analyses. The importance of getting advanced techniques is in accordance ...
Savremen način organizovanja u oblasti uređenja vodotoka i obnavljanja rečnih pojaseva / Novel approach to stream corridor restoration
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2003)
U radu se prikazuje jedan od mogućih modela organizacije obnavljanja narušenih režima prirodnih vodotoka, njihovog priobalja i pribrežja. Navode se i opisuju ključni organizacioni koraci kao što su: pokretanje predloga za ...
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. ...
Water distribution system model calibration using genetic algorithm / Kalibracija matematičkih modela vodovodnih sistema primenom genetskog algoritma
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
Model calibration is an important step in the modelling of water distribution systems. Since calibration is a process of adjusting model parameters so that model results fit best the measured data, it becomes a complex ...
