Numerical study of 3D flow at right-angled confluences with and without upstream planform curvature
(IWA Publishing, 2013)
The purpose of this paper is to study the individual and combined effect of upstream planform curvature and difference in bed elevations at the tributary entrance to the confluence on the flow in the confluence hydrodynamics ...
Modeliranje tečenja preko širokih pragova u burnom režimu / Modelling of supercritical flows over a sequence of broad-crested weirs
(Savez građevinskih inženjera Srbije - Beograd, 1999)
U radu se najpre razmatraju problemi matematičkog i numeričkog modeliranja tečenja preko širokih pragova u burnom režimu. Ovi problemi su vezani za pojavu nagle lokalne promene dubine uzvodno od pragova (pojavu hidrauličkog ...
Određivanje trajektorije kamena u tekućoj vodi / Determination of a stone particle trajectory in the flowing water
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2002)
U ovom radu prikazana je metodologija proračuna trajektorije kamena u tekućoj vodi. Analizirani su faktori koji utiču na dužinu trajektorije, odnosno na vreme tonjenja i domet ispuštenog zrna. To su: početna dubina sa koje ...
Determination of a Stone particle trajectory in the flowing water / Određivanje trajektorije kamena u tekućoj vodi
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2002)
Trajectory of a stone particle released into the flowing water is determined The length of the particle trajectory, i.e. the duration of sinking and the distance traveled by the released particle, is analyzed in terms of ...
Epilithic diatoms in environmental bioindication and trout farm’s effects on ecological quality assessment of rivers
(Elsevier, 2021)
The main aim of this study was to investigate the application of benthic diatoms and the efficiency of diatom indices in water ecological assessment of rivers in Serbia, as well as the influence of trout farms on rivers ...
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, ...
A New Approach for Trend Assessment of Annual Streamflows: a Case Study of Hydropower Plants in Serbia
(Springer Netherlands, 2017)
The authors propose a new approach for trend assessment that takes into account long-term periodicity of annual flows. In particular, analysis is performed of annual flows recorded at the locations of 30 operating and ...
A sustainability analysis of an incineration project in Serbia
(Waste Management & Research, 2013)
The only option for municipal solid waste (MSW) treatment adopted so far in Serbia is landfilling. Similarly to other south-eastern European countries, Serbia is not recovering any energy from MSW. Fifty percent of electricity ...
Forecasting of THM concentration in distribution water supplying network / Prognoza sadržaja trihalometana u distribucionoj vodovodnoj mreži
(Savez inženjera i tehničara Srbije, Beograd, 2012)
The presence of free chlorine is a prerequisite for the formation of THM's, The THM concentration increases with extending the reaction time between natural organic matter and disinfectants, which means that these products ...
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 ...
