Metoda za odredjivanje protoka na ulazu u turbine HE "Djerdap 2"
(Srpsko društvo za odvodnjavanje i navodnjavanje i Akademija inženjerskih nauka Srbije, 2021)
Protok vode kroz turbinu je jedna od najznačajnijih veličina u postupku upravljanja radom agregata, ali je istovremeno i veličina koju je najteže pouzdano izmeriti. Merna nesigurnost je obično veća nego kod merenja ostalih ...
Aspects of water velocity measurements with acoustic Doppler velocimetry / Aspekti merenja brzine vode akustičnom Dopler anemometrijom
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
The paper analyzes the various aspects of acoustic Doppler anemometry usage, for the measurements of instantaneous water velocity, in the context of the problems of hydraulic engineering. Physical principle of the measuring ...
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 ...
Effects of slope and surface orientation on calculation of reference evapotranspiration based on Penman-Monteith equation / Uticaj nagiba i orijentacije površine na proračun referentne evapotranspiracije primenom Penman-Monteith metode
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Evapotranspiration is an important component of hydrological balance and it is calculated based on reference evapotranspiration (ET0). In the last fifty years there have been many empirical models developed for determining ...
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 ...
Numerical modelling and simulation of pollutant transport in Neretva / Numeričko modeliranje i simulacija transporta zagađenja Neretvom
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
Waste water, discharged into the river system is in processes of transport and mixing. After fully cross mixing, the pollution transport is one-dimensional. The aim of the study was to model the discharge, salinity and ...
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 ...
Flood control of tailings-dam reservoirs / Problemi evakuacije velikih voda iz jalovišnih akumulacija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
This paper analyzes the problems of flood control for the tailings-dams reservoirs, having in mind the significant rise of the flow and volume of observed flood waves, and increasingly stringent criteria for safety of high ...
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. ...
