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 ...
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 ...
Supercritical flow in circular-conduit bends / Burno tečenje u krivini provodnika kružnog poprečnog preseka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2013)
Complex flow pattern occurring in a circular conduit bend with supercritical flow is analyzed. The research was done by a scale (physical hydraulic) model, and a numerical model developed in ANSYS (Fluent) surrounding. The ...
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 ...

Marginal distributions of daily precipitation in Serbia / Marginalne raspodele kumulativnih dnevnih padavina na prostoru Srbije
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2010)
This paper presents a part of results of the continuous efforts of the authors to promote, improve and popularize structural analyses of daily hydrological and meteorological series, first introduced by professor Vujica ...
Near real time data assimilation of numerical simulation model for Danube river from Novi Sad to Iron Gate I: Test results / Asimilacija računskog modela Dunava od Novog Sada do HE "Đerdap 1" u približno realnom vremenu - rezultati testiranja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
In this paper, a novel data assimilation method for operational reservoir management on the Danube river section between Novi Sad and Iron Gate I is presented. The proposed data assimilation method allows discharges of ...
