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 ...
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 ...
Polyurethane foam acoustic insulation / Akustička izolacija na bazi poliuretanskih pena
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2009)
Polyurethane based products are often used in civil engineering. Apart to regular use of this material in thermal insulation purposes, polyurethane is widely used in field of acoustic insulation. Usage of modern ...
Milutin Milanković (1879-1958): First doctor of engineering among the Serbs / Milutin Milanković (1879-1958) - prvi doktor tehničkih nauka među Srbima
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2009)
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 ...
Short-term behaviour of reinforced recycled aggregate concrete beams / Ponašanje armiranobetonskih greda od betona na bazi recikliranog agregata pod kratkotrajnim opterećenjem
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
Recycling of waste concrete is one of the sustainable solutions for growing waste disposal crisis and depletion of natural aggregate sources. As a result of that process, recycled aggregate (RCA) is produced and it is used ...
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 ...
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 ...
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 ...
