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 ...
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, ...
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 ...
Estimating demands for water supply under reduced pressure / Procena ukupnih potreba za vodom pri smanjenju pritiska
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
Many water utilities, continue to operate inefficient water distribution systems (WDSs) with a significant amount of water and revenue losses. This paper investigates the potentials of the available pressure management ...
Numerical simulation of the flow field in the vicinity of an intake structure / Numerička simulacija strujnog polja u blizini vodozahvata
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2010)
This paper deals with the analysis of the flow field in the vicinity of an intake structure. It is shown that flow and psamological characteristics can be determined successfully by 2D and 3D numerical models. Determining ...
New method for complex water resources systems reliability evaluation / Novi pristupi pri određivanju pouzdanosti složenih vodoprivrednih sistema pod pritiskom
(Savez građevinskih inženjera Srbije, Beograd, 2011)
A new methodology for water resources systems reliability evaluation is presented. The proposed methodology considers both: mechanical reliability (probability of pipe failure) and reliability of hydraulic parameters in ...
Low cost arsenic removal from aqueous solution by adsorption / Uklanjanje arsena iz vode adsorpcijom na nekonvencionalnim materijalima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
This paper deals with arsenic removal from water by adsorption with unconventional materials: natural materials (zeolite, bentonite, sepiolite, limonite, pyrolusite), waste materials (waste iron slag, waste sand filter) ...
Methodologies for Pre-Validation of Biofilters and Wetlands for Stormwater Treatment
