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 ...
The pressurized pipelines: The risk of bidirectional fluid exchange with the environment / Cevovodi pod pritiskom i rizik od razmene fluida sa okolinom
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The pressurized pipeline fluid transport is supposed to be cheap, reliable and efficient. If buried, pipelines are hard observable by means of leaks, minor cracks and asset damages. These phenomena can influence both the ...
Estimating the capacity of double side-channel spillways / Procena propusne moći dvostrukog bočnog preliva
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
A double side-channel spillway consists of two spillways, with channels joining into a common single branch, noting that for some specific site conditions such arrangements may suit better than the conventional one-side-channel ...
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 ...
Mathematical modelling of ecological processes in reservoirs of hydroenergetic systems / Modeliranje ekoloških procesa u akumulacijama hidroenergetskih sistema
(JP Elektroprivreda Srbije, Beograd, 2009)
Prediction of dynamic changes of water quality in lakes and reservoirs is very important from the aspects of planning and exploitation of hydroenergetic systems. That is the main reason for increasing development of ...
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 ...
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 ...
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 ...
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 ...
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 ...
