Expert system for operational planning and implementation flood control / Ekspertni sistemi za planiranje i operativno sprovođenje odbrane od poplava
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
In the Theory of reliability there is well known fact: in the control chain of decision-making and management the least reliable link is - man. It is particularly evident in emergency situations, when one need to make a ...
Proračun linije nivoa u neprizmatičnom koritu za veliku vodu primenom metode razmene količine kretanja između glavnog korita i plavnih površina (primer korita jednostavne geometrije) / Water profile computations in non-prismatic compound channels with simple cross-sectional geometry using exchange discharge model
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2017)
Cilj ovog rada je da se stručnoj javnosti prikažu mogućnosti modela razmene količine kretanja (MRKK) u proračunima linije nivoa duž neprizmatičnih korita za veliku vodu (KVV). Reč je o modelu koji je već uspešno primenjivan ...
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 ...
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 ...
Water quality impact assessment of the River Ibar hydropower system / Analiza uticaja izgradnje sistema HE na Ibru na kvalitet vode
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
Water quality impact assessment of the River Ibar hydropower cascade project is analyzed in this paper, as one of possible aspects of environmental impact assessment. Based on available data provided by authorized institutions, ...
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 ...
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 ...
Impacts of partial water re-routing from the Buna and Bregava catchments in the catchment of Trebišnjica river / Uticaj delimičnog prevođenja voda iz slivova Bune i Bregave u sliv Trebišnjice
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
The Trebišnjica Hydrosystem is one of the most complex development projects in that part of Europe known as the Dinaric Karst area. In this area, water is the only important and valuable natural resource and base for ...
