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 ...
Experimental investigation of transformation of micropollutants in biofilters: Raingardens / Eksperimentalno istraživanje transformacije mikropolutanata u biofilterima - raingardens
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2013)
Biofilters (bio-retention ponds or rain gardens) are increasingly being used as a system for the storm water treatment in urban areas, because they manage to mitigate the peaks of storm rains and floods, and have shown ...
Mathematical modeling of the sewage system for improvement of the system and the WWTP in the Maribor city / Matematički model kanalizacionog sistema Maribora radi unapređenja kanalizacionog sistema i rada PPOV-a
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
This paper discuss conditions and constraints for WWTP operation using mathematical modeling of the sewage system for the city of Maribor. Using results of SWMM model accounting for various phases of urban surface runoff ...
Nitrate removal from water by biological denitrification / Biološka denitrifikacija u pripremi vode za piće
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2011)
Ground water pollution by nitrate from routine agricultural practices is a common and growing problem in the major agricultural areas of the world. The concentration of nitrates in these areas may exceed the maximal limited ...
Numerical modeling of two phase flow (water-air) after air injection into the water / Modeliranje dvofaznog strujanja (vode i vazduha) nakon utiskivanja vazduha u vodu
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
One of available lake restoration technologies is injection of compressed air or oxygen into a hypolimnion, promoting vertical mixing of water and dissolution of oxygen. A numerical model has been developed for simulation ...
Uncertainty of infrastructure leakage index (ILI) / O neodređenosti infrastruktuknog indeksa gubitaka - ILI
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
In many water systems, especially in developing countries, data on the elements of the system, flow measurements and water consumption have great uncertainty. This uncertainty in the further calculations is propagated to ...
Numerical modeling of water temperature changes in reservoir Celije / Modeliranje sezonskih promena temperature vode akumulacije Ćelije
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2013)
This paper presents the results of measurements and numerical modeling of water temperature changes in reservoir Celije in the period from April to October 2012. Reservoir Celije on the river Rasina, for many years attracts ...
Rainfall runoff drainage and traffic safety in urban conditions / Odvođenje kišnog oticaja u gradovima i sigurnost saobraćaja
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
The paper discusses the possibilities to evaluate the effects of applying different criteria for design of surface drainage systems on the reliability of these systems. The reliability is expressed using the safety faktor ...
The Belgrade waste water system during severe rainfall / Beogradski kanalizacioni sistem u uslovima ekstremnih padavina
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The Belgrade waste water system started being built more than 100 years ago. It is getting larger in accordance to urban development aimed at collecting most of waste water including rainfall runoff and communal and ...
Enhancement of digital elevation models for overland flow network delineation in urban catchments / Poboljšanje digitalnog modela terena za delineaciju površinskog tečenja na urbanim slivovima
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
Algorithms to prepare Digital Elevation Models (DMTs) for hydraulic analysis are common practice; these are often called DMT enhancement algorithms, and are frequently the first step of the analysis to extract overland ...
