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.
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, ...
Measurements, calibration of rainfall-runoff models and assessment of the return period of flooding events at urban catchment Kumodraž 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 ...
Ultrasonic flow measurement method: Working principles and use in water distribution and sewer systems / Ultrazvučna merila protoka u sistemima vodovoda i kanalizacije
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
Flow metering in Water Supply and Sewer Systems (WSSS) is the essential need Technical reason are the water balance control and the operational management. In the scope of inevitable privatizations (in Serbian environment) ...
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 ...
