Automatska podela vodovodne mreže na osnovne zone bilansiranja na primeru Požarevca
(Voda i sanitarna tehnika, 2016)
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 ...
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 ...
Air-water flow on a labyrinth spillway
(Serbian Water Pollution Control Society, Belgrade, 2014)
The design of the Beni Slimane Dam (Medea Province, Algeria) was verified by scale model analyses, conducted on two separate scale models: a partial model of labyrinth spillway and a complete model of spillway structures. ...
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 ...
Instability analysis of the air-water flow in porous medium / Analiza pojave nestabilnosti kod dvofaznog strujanja u poroznoj sredini
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
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 ...
Scale modeling of the Bouzina Dam flood mitigation structures
(Serbian Water Pollution Control Society, Belgrade, 2014)
The design of the RCC (roller-compacted concrete) Bouzina Dam (Batna Province, Algeria) was verified using a scale model. The length scale of the physical model was 1:40 and the hydraulic parameters were scaled applying ...
Analysis of hydrodynamic pressures in the stilling basin of an earth dam
(Serbian Water Pollution Control Society, Belgrade, 2015)
The stilling basin is one of the most frequently used energy dissipation structures due to highly-efficient energy dissipation of the main stream through the secondary turbulent flow in the hydraulic jump roller formed ...
