Analysis of cascaded hydropower system control in Simulink / Analiza upravljanja kaskadnim HES pomoću Simulinka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
Hydropower Systems (HES) fall into the 'green' and renewable energy sources. Unfortunately, most of the quality sites are either already occupied or have significant physical limitations, so lately, utilization of the less ...
Estimating demands for water supply under reduced pressure / Procena ukupnih potreba za vodom pri smanjenju pritiska
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
Many water utilities, continue to operate inefficient water distribution systems (WDSs) with a significant amount of water and revenue losses. This paper investigates the potentials of the available pressure management ...
Low cost arsenic removal from aqueous solution by adsorption / Uklanjanje arsena iz vode adsorpcijom na nekonvencionalnim materijalima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
This paper deals with arsenic removal from water by adsorption with unconventional materials: natural materials (zeolite, bentonite, sepiolite, limonite, pyrolusite), waste materials (waste iron slag, waste sand filter) ...
Numerical simulation of the flow field in the vicinity of an intake structure / Numerička simulacija strujnog polja u blizini vodozahvata
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2010)
This paper deals with the analysis of the flow field in the vicinity of an intake structure. It is shown that flow and psamological characteristics can be determined successfully by 2D and 3D numerical models. 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 ...
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 ...
Effect of bed elevation discordance on momentum-flux from tributary flow and parameter values in 1d confluence models / Uticaj podvodnih kaskada na raspored protoka količine kretanja na ušću i vrednosti parametara u linijskim modelima ušća
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
Bathymetric surveys in confluences of both alluvial and mountaneous rivers have shown that a bed step at a tributary entrance to the confluence is a common morphological feature and that it may also develop in the main-river. ...
Long-term changes of annual and seasonal flows: A case of the Sava River / Dugoročne promene godišnjih i sezonskih proticaja - primer reke Save
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
This paper investigates the long-term changes in the hydrological time series. For this purpose, we use the trend analysis. The trend analysis is performed by using the standard Mann-Kendall trend test and by using the ...
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 ...
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, ...
