Determination of a Stone particle trajectory in the flowing water / Određivanje trajektorije kamena u tekućoj vodi
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2002)
Trajectory of a stone particle released into the flowing water is determined The length of the particle trajectory, i.e. the duration of sinking and the distance traveled by the released particle, is analyzed in terms of ...
Comparative analysis of the results obtained with 3d orthogonal and non-orthogonal grids in the 3d-flow models: Part 1 / Uporedna analiza rezultata dobijenih primenom ortogonalnih ineortogonalnih mreža u modelima prostornog tečenja - deo l
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
Application of orthogonal and non-orthogonal grids in numerical models of the three-dimensional flow is considered. A river confluence is chosen as an example due to strong three-dimensional flow effects occurring at the ...
Compiled free surface mathematical models uncertainty propagation / Propagacija neodređenosti kod linijskih modela otvorenih tokova
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Free surface flow is usually simulated by 1D numerical models. This approach assumes flow simplification and requires model calibration in order to reproduce flow characteristics in a realistic way. The calibration and ...
Assessment of the position and dimensions of the ski-jump scour-hole / Procena položaja i dimenzija erozione jame ski odskoka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
This paper is concerned with the ski-jump design, mainly for the large overflow dams. Although the vast scope of literature on this subject exists, there is still a need to compile, elaborate and upgrade available knowledge. ...
Introduction of rain gauges into monitoring of sewer systems: Experiences in choosing, testing and installing the measuring equipment / Uvođenje kišomera u sistem praćenja rada kanalizacionog sistema - iskustva iz faze nabavke, provere i postavljanja
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2005)
Improvement of the Belgrade sewer system performance, necessitated by increasing urbanization, calls for more precise assessment of water balance in the system. In this respect, three rain gauge stations are established ...
Physical methods for waste water treatment: The use of freeze/thaw method with the assistance of microwave radiation for oily water treatment / Fizičke metode za prečišćavanje otpadnih voda - primena metode naizmeničnog mržnjenja i hlađenja i mikrotalasnog zagrevanja za obradu zauljenih voda
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
The main sources of oily waste water are oil- refineries, metal industry and food industry. Any technological process that uses emulsions has to take into consideration also the treatment of the used emulsions. The ultimate ...
Technical and Environmental Aspects of Infrastructure Restoration after Destruction of Bridges in the City of Novi Sad
(International Conference on Environmental Recovery of Yugoslavia – ENRY2001, 2001)
This paper deals with the riverbed morphological and environmental changes induced by destruction of bridges in the city of Novi Sad. Different aspects of infrastructure restoration are discussed. The problem of gas pipeline ...
Water distribution system model calibration using genetic algorithm / Kalibracija matematičkih modela vodovodnih sistema primenom genetskog algoritma
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
Model calibration is an important step in the modelling of water distribution systems. Since calibration is a process of adjusting model parameters so that model results fit best the measured data, it becomes a complex ...
Uncertainties in flood frequency estimation by partial duration series / Neizvesnosti u analizi velikih voda metodom parcijalnih serija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
In hydrologic practice, flood frequency analysis is usually based on fitting a theoretical distribution to observed data series. Flood frequency analysis in hydrologic practice is essentially based on fitting of a theoretical ...
Modified rainfall-runoff model for bifurcations caused by channels embedded in catchments
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2009)
The particularity of 'Vlasina' hydropower plants catchment is a big number of gravitation channels used to collect the water from neighboring natural catchments. The overall catchment size is thus increased, compared to ...
