On design flood levels of the Danube river at Novi Sad / O računskim nivoima vode za zaštitu od poplava na Dunavu kod Novog Sada
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2010)
Protection of the city of Novi Sad from floods relies mainly on levees along the banks of the Danube River. These levees were reconstructed after a great flood in 1965, when they were designed to protect the city from a ...
Thermal behaviour of gravity roller compacted concrete dams, Part One: Thermal field analysis / Termičko ponašanje gravitacionih RCC brana, I deo - proračun temperaturnog polja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
This paper presents 2D and 3D numerical models for unsteady phased thermal analysis of RCC dams. The time evolution of a thermal field has been modeled with actual dam shape, RCC technology and adequate description of ...
Statistical analysis of floods at the Danube and Sava confluence at Belgrade / Statistička analiza velikih voda Dunava i Save na području Beograda
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
The paper presents a methodology for analysis of the coincident annual maximum floods of the Danube and Sava Rivers at their confluence in Belgrade, as a part of the flood control project aimed to provide boundary conditions ...
Analysis of cascaded hydropower system control in Simulink / Analiza upravljanja kaskadnim HES pomoću Simulinka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
Hydropower Systems (HES) fall into the 'green' and renewable energy sources. Unfortunately, most of the quality sites are either already occupied or have significant physical limitations, so lately, utilization of the less ...
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 ...
Flood frequency analysis at gauged sites: Need for a change in approach / Statistička analiza velikih voda na profilima hidroloških stanica - potreba za promenom pristupa
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
In most developed countries, practices and research results are translated into standards or guidelines for flood flow assessment, usually with the compulsory application in the design and exploitation of hydraulic structures ...
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. ...
Energy loss in a circular-conduit bends with supercritical flow / Gubitak energije u krivini kružnog provodnika pri burnom tečenju
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2013)
In this paper the energy loss in a circular conduit bend with supercritical flow is analyzed. Based on the test results obtained by a scale model, the energy-loss coefficient has been determined. Simple empirical relationships ...
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 ...
Mogućnosti aktivne odbrane od poplava upravljanjem uz primenu matematičkih modela - na primeru akumulacije Bočac na Vrbasu / Possibilities for active flood control management with the application of mathematical models - the case study of reservoir Bočac on Vrbas river
(Srpsko društvo za odvodnjavanje i navodnjavanjeAkademija inženjerskih nauka Srbije, 2019)
Sistemi zaštite od poplava spadaju u klasu najvažnijih, najvitalnijih sistema koje čovek gradi, jer su vezani za ciljeve opstanka, rasta i razvoja ljudskog društva. Zato su ti sistemi u stalnom razvoju, kako sa stanovišta ...
