Uncertainty reduction in water distribution network modelling using system inflow data
(Urban Water Journal, 2009)
In water distribution network (WDN) modelling, nodal demand is the sum of flows taken by users associated with a computational node. User demands are not fixed in time; rather they are stochastic. Hence, nodal demand is a ...
Sewer system management in extraordinary events
(Risk Management of Water Supply and Sanitation Systems, 2009)
This paper deals with the problem of sewer system management in extraordinary conditions - by which are included both non-regular and special events. Extreme precipitation, thick layer of snow and its melting, extreme ...
Overland flow and pathway analysis for modelling of urban pluvial flooding
(Journal of Hydraulic Research, 2009)
Research on improving an overland flow model is presented for urban pluvial flooding under the dual-drainage concept where sewer flow dynamically interacts with overland flow. This occurs during heavy storms when the sewer ...
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 ...
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 ...
Consequences of non planned urban development during turbulent times in Serbia - case study of suburb Kumodraz watershed in Belgrade
(Risk Management of Water Supply and Sanitation Systems, 2009)
Development is usually based oil numerous analyses accounting for planning, economy and population assessments as well as urbanism, architectural and civil engineering infrastructure planning and project design. The modern ...
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 ...
