Water mixing in reservoir and water age in the distribution network modelling / Modeliranje mešanja vode u rezervoaru i starosti u distributivnoj mreži
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
The main role of reservoirs is to store the water for periods when consumption is higher then water production, thus increasing the reliability of system. However, the water storage can also lead to water aging, and its ...
Prikaz modela linijskog tečenja u koritu za veliku vodu zasnovanog na razmeni količine kretanja između glavnog korita i plavnih površina / Introduction to an exchange discharge model for compound channel flow modelling
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2015)
Cilj ovog rada je da se stručnoj javnosti prikaže model linijskog tečenja u koritu za veliku vodu koji do sada nije primenjivan u našoj inženjerskoj praksi. Reč je o modelu koji ima dvostruku namenu. Kada se raspolaže ...
Aspects of water velocity measurements with acoustic Doppler velocimetry / Aspekti merenja brzine vode akustičnom Dopler anemometrijom
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
The paper analyzes the various aspects of acoustic Doppler anemometry usage, for the measurements of instantaneous water velocity, in the context of the problems of hydraulic engineering. Physical principle of the measuring ...
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 ...
Effects of slope and surface orientation on calculation of reference evapotranspiration based on Penman-Monteith equation / Uticaj nagiba i orijentacije površine na proračun referentne evapotranspiracije primenom Penman-Monteith metode
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Evapotranspiration is an important component of hydrological balance and it is calculated based on reference evapotranspiration (ET0). In the last fifty years there have been many empirical models developed for determining ...
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 ...
The implementation of the HBV model for flood forecasting in Jadar river basin / Primena modela HBV za hidrološku prognozu na slivu reke Jadar
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
The SMHI\HBV model is used for runoff modelling of the Jadar River basin, for the purpose of hydrological forecasting. The Jadar River is the largest Serbian tributary of the Drina River with an area of 959 km2, and is ...
Seismic hydrodynamic load analysis / Proračun seizmičkih hidrodinamičkih opterećenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
Zangar's method for computation of seismic hydrodynamic loads acting at the inclined contour of a concrete gravity dam, has been reconsidered. Several numerical models are compared with the procedure recommended by Zangar, ...
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 ...
Experimental investigation of transformation of micropollutants in biofilters: Raingardens / Eksperimentalno istraživanje transformacije mikropolutanata u biofilterima - raingardens
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2013)
Biofilters (bio-retention ponds or rain gardens) are increasingly being used as a system for the storm water treatment in urban areas, because they manage to mitigate the peaks of storm rains and floods, and have shown ...
