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 ...
Structural analysis of Jelezovac dam stepped spillway with baffle / Statička analiza stepenastog preliva sa odbojnom gredom na pregradi Jelezovac
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2010)
The concrete gravity dam spillway on the Jelezovac stream is presented. The overflow section of the dam is an original structure, designed as a stepped spillway, with bottom outlets and the modified USBR VI stilling basin ...
SPH method / Rešavanje jednačina kretanja fluida metodom zasnovanom na praćenju fluidnih delića (SPH metoda)
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
The SPH (Smoothed Particle Hydrodynamics) method for solving fluid dynamics equations is presented in this paper. The main aim of this paper is to present theoretical aspects of the method which is used in numerical modelling ...
Comparative analysis of the results obtained with 3d orthogonal and non-orthogonal grids in the 3d-flow models: Part 1 / Uporedna analiza rezultata dobijenih primenom ortogonalnih ineortogonalnih mreža u modelima prostornog tečenja - deo l
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
Application of orthogonal and non-orthogonal grids in numerical models of the three-dimensional flow is considered. A river confluence is chosen as an example due to strong three-dimensional flow effects occurring at the ...
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. ...
Prikaz modela nezavisnih segmenata za proračun linijskog tečenja u koritu za veliku vodu
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2019)
Cilj ovog rada je da našu stručnu javnost upozna sa još jednim modelom za proračun linijskog tečenja u koritu za veliku vodu koji, u proračunu gubitaka energije osim trenja, uzima u obzir i razmenu količine kretanja između ...
Harmonization of development projects in the Drina river basin with environmental conservation requirements / Razvojne projekte na slivu Drine uskladiti sa zahtevima očuvanja životne sredine
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2004)
The implementation of new projects in the Drina river basin will depend on their successful harmonization with the social and ecological environment. The paper discusses the trends which govern the evaluation and approval ...
Analytical models of confluences: A survey and models' assessment / Pregled i ocena analitičkih modela ušća
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Assumptions upon which development of 1D models of free-surface flow rest are not valid at open-channel junctions. Thus, the 1D flow equations cannot be used for calculation of upstream flow depths, or water levels in a ...
