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 ...
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 ...
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 ...
Streamflow measurement by salinity dilution method / Merenje protoka u otvorenim tokovima metodom razblaženja koncentracije soli
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Streamflow measurement often requires a clearly structured measurement reach. Velocity distribution can then be measured using a current meter or by constructing a hydraulic section control (weirs or flumes). However, in ...
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 ...
Instability analysis of the air-water flow in porous medium / Analiza pojave nestabilnosti kod dvofaznog strujanja u poroznoj sredini
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
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 ...
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 ...
Estimating double side-channel spillway capacity / Procena propusne moći dvostrukog bočnog preliva
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The capacity of the double side-channel spillway, consisting of the two spillways, with channels joining into a common single branch, is estimated in this paper. For the specific site conditions, such an arrangement may ...
Flood risk mapping / Kartiranje rizika od poplava
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
The paper considers the methodology for the mapping flood zones, flood damages and flood risk. The emphasis is on the development of synthetic flood damage functions, used for the determination of the expected annual ...
