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 ...
Numerical modelling and simulation of pollutant transport in Neretva / Numeričko modeliranje i simulacija transporta zagađenja Neretvom
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
Waste water, discharged into the river system is in processes of transport and mixing. After fully cross mixing, the pollution transport is one-dimensional. The aim of the study was to model the discharge, salinity and ...
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 ...
Methodology for sequent depth estimation for converging stepped-chute stilling basins / Metodologija proračuna spregnutih dubina kod umirujućih bazena neprizmatičnih stepenastih brzotoka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
The influence of converging stepped spillways on the dimensions of the stilling basins for RCC dams was examined, based on the results of physical modeling, existing empirical expressions, and basic laws of fluid mechanics ...
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 ...
Flood control of tailings-dam reservoirs / Problemi evakuacije velikih voda iz jalovišnih akumulacija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
This paper analyzes the problems of flood control for the tailings-dams reservoirs, having in mind the significant rise of the flow and volume of observed flood waves, and increasingly stringent criteria for safety of high ...
Sizing and calibration of urban stormwater infiltration system in Belgrade / Dimenzionisanje i kalibracija sistema za infiltraciju kišnice na urbanom slivu u Beogradu
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
This work shows a way to size and calibrate parameters of urban stormwater collection and treatment infiltration system. Its design allows collection of stormwater runoff events for a 2 year return period and infiltration ...
