Urban drainage simulation model sensitivity analysis on runoff control elements / Analiza osetljivosti elemenata za kontrolu oticaja u simulacionom modelu kišne kanalizacije urbanog sliva
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2012)
In current design practice, regardless if classic or sustainable drainage concept approach is applied in modeling of rainfall-runoff process, various drainage elements are used (gullies, catch basins, grates or slotted ...
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 ...
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 ...
Detekcija nivoa u laboratorijskim kanalima primenom tehnike obrade slika
(Srpsko društo za odvodnjavanje i navodnjavanje, 2019)
Određivanje i praćenje promena nivoa vode u laboratorijskim uslovima primenom tradicionalnih mernih metoda opterećeno je raznim nedostacima: tačnost, frekvencija uzorkovanja, inertnost mernog uređaja i osetljivost na spoljne ...
Corrosion of an austenite and ferrite stainless steel weld / Korozija zavarenog spoja austenitnog i feritnog nerđajućeg čelika
(Srpsko hemijsko društvo, Beograd, 2011)
Dissimilar metal connections are prone to frequent failures. These failures are attributed to the difference in the mechanical properties across the weld, the coefficients of thermal expansion of the two types of steels ...
Speeding up the water distribution network design optimization using the Delta Q method
(IWA Publishing, 2016)
To optimize the design of a water distribution network (WDN), a large number of possible solutions need to be examined; hence computation efficiency is an important issue. To accelerate the computation, one can use more ...
Experimental Study on Scour at a Sharp-Nose Bridge Pier with Debris Blockage
(American Society of Civil Engineers (ASCE), 2018)
Previous experimental research on the effects of debris on pier scour has focused primarily on circular and rectangular piers with debris present just under flow free surface. Debris-induced scour around sharp-nose piers, ...
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 ...
Stochastic structure of annual discharges of large European rivers
(Versita, 2015)
Water resource has become a guarantee for sustainable development on both local and global scales. Exploiting water resources involves development of hydrological models for water management planning. In this paper we ...
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, ...
