Water leakage management in water supply systems / Upravljanja gubicima u vodovodnim sistemima
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2008)
Leakage reduction and reduction of un-rationalized water usage is the basis for the effective operation of Water Utility. Current practice of reactive (or passive) leakage reduction should be replaced by proactive search ...
Measurement, calibration of rainfall-runoff models and assessment of the return period of flooding events at urban catchment Kumodraz in Belgrade
(IWA Publishing, 2002)
For the purpose of re-design and improvement of the combined sewer system at the Kumodraz catchment in Belgrade, measurements of rainfall and runoff at the catchment were established in late 1997, Observed data are used ...
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 ...
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 ...
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 ...
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 ...
Određivanje trajektorije kamena u tekućoj vodi / Determination of a stone particle trajectory in the flowing water
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2002)
U ovom radu prikazana je metodologija proračuna trajektorije kamena u tekućoj vodi. Analizirani su faktori koji utiču na dužinu trajektorije, odnosno na vreme tonjenja i domet ispuštenog zrna. To su: početna dubina sa koje ...
Determination of a Stone particle trajectory in the flowing water / Određivanje trajektorije kamena u tekućoj vodi
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2002)
Trajectory of a stone particle released into the flowing water is determined The length of the particle trajectory, i.e. the duration of sinking and the distance traveled by the released particle, is analyzed in terms of ...
Roller compacted concrete (RCC) in dam construction, Part four: Construction, quality control and economic issues / Primena valjanog betona u izgradnji brana, IV deo - građenje, kontrola kvaliteta i ekonomski aspekti
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
The last of the four-paper serial on RCC dams refers to construction, quality-control and economic issues. The first part deals with the most important construction features, such as: concrete preparation, transportation, ...
