Comparative analysis of the results obtained with 3d orthogonal and non-orthogonal grids in the 3d-flow models: Part 1 / Uporedna analiza rezultata dobijenih primenom ortogonalnih ineortogonalnih mreža u modelima prostornog tečenja - deo l
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
Application of orthogonal and non-orthogonal grids in numerical models of the three-dimensional flow is considered. A river confluence is chosen as an example due to strong three-dimensional flow effects occurring at the ...
Compiled free surface mathematical models uncertainty propagation / Propagacija neodređenosti kod linijskih modela otvorenih tokova
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Free surface flow is usually simulated by 1D numerical models. This approach assumes flow simplification and requires model calibration in order to reproduce flow characteristics in a realistic way. The calibration and ...
Analytical optimization method for water supply systems modeling / Analitička optimizaciona metoda u modeliranju vodovodnih sistema
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
The consequence of an uncertainty of water supply systems models’ parameters is the discrepancy between simulation results and measurement data. The best values of parameters that can be obtained from available measurement ...
Water losses reduction by managing operational pressure / Upravljanje radnim pritiskom u cilju smanjenja gubitaka
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
Managing operational pressure is essential for effective reduction of water losses, so system operation is directed towards its maximum reduction with fulfilling the demand of each customer. With this objective, the variable ...
Numerical simulation of hydraulic consequences of dam failures on coal-ash disposal sites / Numerička simulacija hidrauličkih posledica havarija brana na pepelištima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2003)
The objectives of numerical simulation of hydraulic consequences of dam failure on coal-ash disposal sites are to define the scope of flooding consider possibility of early warning, and undertake the appropriate protective ...
Drainage of bridge decks in urban environment / Odvodnjavanje mostova u urbanim sredinama
(Savez građevinskih inženjera Srbije, Beograd, 2009)
Storm water drainage from buildings, motorways, airports or bridges is a complex task for design engineers. Bridge design deals not only with structural aspects, but with driving safety during heavy rainfall as well. To ...
Measurements in Belgrade sewer system / Merenja na Beogradskom kanalizacionom sistemu
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The installation of monitoring system at 8 sewer outlets of Belgrade Sewer System has started during 2007. In this paper the extension of that process is presented, where 5 new monitoring sites were equipped and new ...
Hydraulic model study of turbulent flow measurement in sewer pipes conjunction / Hidraulička modelska ispitivanja merenja protoka na spoju kolektora sa silovitim tečenjem
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
This paper presents capabilities and benefits of use of physical models for flow analysis in large sewer pipes and conjoining objects. A group of objects pertaining to the Belgrade Sewer System is modeled and results are ...
Water supply systems modeling: Optimization of model parameters using PEST method / Modeliranje vodovodnih sistema - optimizacija parametara modela primenom PEST metode
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2004)
One of the reasons for discrepancy between results of the Water Supply Systems hydraulic simulation and measurement data is the uncertainty of values of mathematical model parameters. Because of that, the best possible ...
The effect of land use schematization on result of surface runoff modeling with the example of Miljakovac catchments / Analiza uticaja nepoznavanja namene površina na rezultate simulacije modela kišnog oticaja na primeru Miljakovac
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2005)
Experimental catchments Miljakovac has been used in 1980-es for field studies of rainfall-runoff processes. The most accurate analysis of flow in storm sewer systems can be achieved when there is a land use map defined in ...
