Marginal distributions for daily runoff series at representative profiles in Serbia / Marginalne raspodele dnevnih proticaja na reprezentativnim profilima u Srbiji
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2010)
Previous analyses (Radić & Mihailović, 2006, [8 i [9]) based on new methodology showed the advantages of complete 365 daily data sets analyses against monthly or characteristic daily data. Advantages were demonstrated for ...
Nitrate removal from water by biological denitrification / Uklanjanje nitrata iz vode za piće primenom biološke denitrifikacije
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
Ground water pollution by nitrate from routine agricultural practices is a common and growing problem in the major agricultural areas of the world. The concentration of nitrates in these areas may exceed the maximal limited ...
Uncertainty of infrastructure leakage index (ILI) / O neodređenosti infrastruktuknog indeksa gubitaka - ILI
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
In many water systems, especially in developing countries, data on the elements of the system, flow measurements and water consumption have great uncertainty. This uncertainty in the further calculations is propagated to ...
Algorithm for water distribution network segmentation using existing isolation valves / Algoritam za segmentaciju vodovodne mreže pomoću postojećih izolacionih zatvarača
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
Dividing a complex water distribution network (segmentation) on smaller zones, with defined entry and exit points, is a precondition for better water loss management. In order to obtain these zones, often called District ...
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 ...
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 ...
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 ...
Water profile computations in non-prismatic compound channels with simple cross-sectional geometry using exchange discharge model / Proračun linije nivoa u neprizmatičnom koritu za veliku vodu primenom metode razmene količine kretanja između glavnog korita i plavnih površina - primer korita jednostavne geometrije
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
The paper aims at presenting possibilities of the exchange discharge model (EDM) in 1D non-prismatic compound channel flow modelling to the Serbian hydraulic engineering community. The model has been already successfully ...
