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 ...
Simulation of transcritical flow in pipe/channel networks
(ASCE - American Society of Civil Engineers, 2004)
Using finite difference methods in conjunction with the reduced momentum equation and applying boundary condition structure inherent to subcritical flow to all regimes, is an approach that enables efficient numerical ...
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 ...
Application of 2D and 3D modelling in bay entrance design / Oblikovanje ulaza u zaliv primenom modela ravanskog i prostornog tečenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
Bays suffer from siltation, which is a natural process that cannot be avoided. The main cause of this process is mixing of the river-water containing suspended sediment and the river-bay water. High costs of maintenance - ...
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 ...
Introduction of rain gauges into monitoring of sewer systems: Experiences in choosing, testing and installing the measuring equipment / Uvođenje kišomera u sistem praćenja rada kanalizacionog sistema - iskustva iz faze nabavke, provere i postavljanja
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2005)
Improvement of the Belgrade sewer system performance, necessitated by increasing urbanization, calls for more precise assessment of water balance in the system. In this respect, three rain gauge stations are established ...
MAC1GUM
(Građevinski fakultet, Univerziteta u Beogradu, 2003)
Softver (program) za proračun linijskog neustaljenog tečenja gustih mešavina u otvorenim tokovima. Nagib linije energije računa se za ustaljeno, blago promenljivo nejednoliko tečenje Herschel-Bulkley-jevog nenjutnovskog fluida.
