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. ...
Thermal behaviour of gravity roller compacted concrete dams, Part One: Thermal field analysis / Termičko ponašanje gravitacionih RCC brana, I deo - proračun temperaturnog polja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
This paper presents 2D and 3D numerical models for unsteady phased thermal analysis of RCC dams. The time evolution of a thermal field has been modeled with actual dam shape, RCC technology and adequate description of ...
Roller compacted concrete in dam construction, part III: Design / Primena valjanog betona u izgradnji brana - III deo: Projektovanje
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2004)
After the chronological review of the RCC dams development, and the analysis of the RCC components in the previous articles of this serial, this paper presents the most important issues of the gravity RCC dams design. In ...
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 ...
Water supply systems modeling: Optimization of model parameters using PEST method / Modeliranje vodovodnih sistema - optimizacija parametara modela primenom PEST metode
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2004)
One of the reasons for discrepancy between results of the Water Supply Systems hydraulic simulation and measurement data is the uncertainty of values of mathematical model parameters. Because of that, the best possible ...
Improvement of the flow measuring methodology with the flat electromagnetic velocity probes / Unapređenje metodologije merenja protoka pomoću ravnih elektromagnetnih senzora brzine
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
One of the commonly used approaches, for the flow measurements in open chanel hydraulic systems, is to measure one depth and use the stable Q-H relationship to compute the flow rate. If this method is inappropriate, the ...
On design flood levels of the Danube river at Novi Sad / O računskim nivoima vode za zaštitu od poplava na Dunavu kod Novog Sada
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2010)
Protection of the city of Novi Sad from floods relies mainly on levees along the banks of the Danube River. These levees were reconstructed after a great flood in 1965, when they were designed to protect the city from a ...
Application of numerical models for improvement of wellhead protection management: Case study: Korbovo wellhead / Primena numeričkih modela za optimizaciju rada bunarske zaštite eksploatacionih bunara - primer izvorišta Korbovo
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
Advanced mathematical models of groundwater flow provide exceptional support in designing of new wellheads, but also optimization analyses of the existing groundwater resources management. However, for reliable forecasts ...
Optimization of pressurized pipe networks modelled with ΔQ method / Optimizacija mreža pod pritiskom modeliranih ΔQ metodom
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2013)
Efficiency of optimization of water networks in terms of expenditure of computer running time depends on the speed of the hydraulic calculations. In this paper use of the ΔQ method for network calculation, was tested on ...
Procena krive protoka i rekonstrukcija poplavnog talasa u dubokom koritu sa uskim plavnim površinama / Estimation of the stage-discharge curve and reconstruction of the flood hydrograph in a deep river channel with narrow floodplains
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2021)
U ovom radu razmatra se svrsishodnost primene metode razmene količine kretanja za procenu krive protoka i rekonstrukciju talasa velikih voda u dubokim koritima za veliku vodu koja imaju uske plavne površine. Ovo pitanje ...
