Primena modela razmene količine kretanja u analizi uticaja geometrije i hidrauličkih otpora na osnovne odlike tečenja u koritu za veliku vodu / Study of the influence of channel geometry and hydraulic resistance on flow characteristics in compound channels with the exchange discharge method
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2015)
U radu je sproveden niz numeričkih ogleda sa ciljem da se utvrdi kako geometrija korita za veliku vodu (KVV) i rapavost plavnih površina utiču na razmenu količine kretanja (RKK) između glavnog korita i plavnih površina i ...
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 ...
Estimating double side-channel spillway capacity / Procena propusne moći dvostrukog bočnog preliva
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The capacity of the double side-channel spillway, consisting of the two spillways, with channels joining into a common single branch, is estimated in this paper. For the specific site conditions, such an arrangement may ...
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 ...
Categories of reliability that should be analized during the planning and operation of water resources systems / Kategorije pouzdanosti koje se moraju proveravati tokom planiranja i korišćenja vodoprivrednih sistema
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
From the standpoint of reliability - a key indicator of the probabilistic effectiveness of systems - water resources systems (WRS) belong to the class of the most sensitive system with multiple categories of reliability. ...
Improvement of the flow measuring methodology with the flat electromagnetic velocity probes / Unapređenje metodologije merenja protoka pomoću ravnih elektromagnetnih senzora brzine
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
One of the commonly used approaches, for the flow measurements in open chanel hydraulic systems, is to measure one depth and use the stable Q-H relationship to compute the flow rate. If this method is inappropriate, the ...
Application of numerical models for improvement of wellhead protection management: Case study: Korbovo wellhead / Primena numeričkih modela za optimizaciju rada bunarske zaštite eksploatacionih bunara - primer izvorišta Korbovo
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
Advanced mathematical models of groundwater flow provide exceptional support in designing of new wellheads, but also optimization analyses of the existing groundwater resources management. However, for reliable forecasts ...
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 ...
