Increase of the effectiveness of the reservoirs during the flood control: On the example of Trebišnjica Hydrosystem / Povećanje efikasnosti upravljanja akumulacijama u periodu odbrane od poplava - na primeru Hidroenergetskog sistema na Trebišnjici
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
As a consequence of the more extreme hydrological phenomena (increasing of high water and reduction of low water regimes and extension of their duration) water storage reservoirs get demanding requirements to be used for ...
Urban drainage simulation model sensitivity analysis on runoff control elements / Analiza osetljivosti elemenata za kontrolu oticaja u simulacionom modelu kišne kanalizacije urbanog sliva
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2012)
In current design practice, regardless if classic or sustainable drainage concept approach is applied in modeling of rainfall-runoff process, various drainage elements are used (gullies, catch basins, grates or slotted ...
Forecasting of THM concentration in distribution water supplying network / Prognoza sadržaja trihalometana u distribucionoj vodovodnoj mreži
(Savez inženjera i tehničara Srbije, Beograd, 2012)
The presence of free chlorine is a prerequisite for the formation of THM's, The THM concentration increases with extending the reaction time between natural organic matter and disinfectants, which means that these products ...
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 ...
Corrosion of cannon 75/27, model 1911. déport, from the collection of the Military Museum in Belgrade / Korozija topa 75/27, model 1911. deport iz kolekcije Vojnog muzeja u Beogradu
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2012)
This paper analyzes the state of the French Cannon 75/27 model 1911. Déport made of steel. The amount of non-corroded materials, the presence of cracks and other defects in the cannon were determined by the radiographic ...
Povećanje efikasnosti upravljanja akumulacijama u periodu odbrane od poplava - na primeru hidroenergetskog sistema na Trebišnjici / Increase of the effectiveness of the reservoirs during the flood control - on the example of Trebišnjica hydrosystem
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2012)
Postepeno pogoršanje ekstremnih hidroloških fenomena – povećanje talasa velikih voda i smanjenje malih voda i produženje njihovog trajanja – postavlja sve zahtevnije uslove da se akumulacije koriste za aktivnu odbranu ...
Controls at river confluences with discordant beds / Uticajni činioci na rečnim ušćima sa izdignutim dnom pritoke
(Savez građevinskih inženjera Srbije, Beograd, 2012)
The role of four parameters that are controlling river confluence hydrodynamics at discordant beds confluences is investigated using 3D numerical model. These are: the junction angle α, the momentum-flux ratio between the ...
Different approach for calculation of inflow on storm water sewer pumping station: Case study KCS Nova 1 on New Belgrade / Mogućnosti za proračun protoka na kišnoj kanalizacionoj crpnoj stanici - primer KCS Nova 1, Novi Beograd
(Savez inženjera i tehničara Srbije, Beograd, 2012)
In the process of making mathematical models, a common problem is lack or missing data that could be used for calibration and verification of the model. In that case, we have to somehow use available data to calculate the ...
Concave Antiprisms of Second Sort with Regular Polygonal Bases
(Novi Sad: Faculty of Technical Sciences, University of Novi SadNovi Sad: Serbian Society for Geometry and Graphics (SUGIG), 2012)
The paper discusses determining the positions and spatial coordinates of the vertices of polyhedral structures - concave antiprisms of second sort. These polyhedra originate from folding the double row strip of equilateral ...
Hydraulic design of morning glory spillway with a deflector upstream of the vertical bend / Određivanje dimenzija šahtnog preliva empirijskim jednačinama
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
Hydraulic design of shaft spillways (morning-glory spillways) with flow deflector before the vertical bend is considered. Based on the physical hydraulic model investigations of several structures and available experience ...
