Water leakage management in water supply systems / Upravljanja gubicima u vodovodnim sistemima
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2008)
Leakage reduction and reduction of un-rationalized water usage is the basis for the effective operation of Water Utility. Current practice of reactive (or passive) leakage reduction should be replaced by proactive search ...
State-of-the-art analysis of irrigation water requirement / Sa vremena analiza potrebnih količina vode za navodnjavanje
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
Two ways of assessing irrigation water requirements are analyzed in the paper. The relationship between income and outcome water is reconstituted by the water balance equation, and the need for irrigation is determined. ...
Integrated management of the urban water cycle: General concepts / Integralno upravljanje gradskim vodama - generalni koncept
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2008)
This paper presents an overview of current and prospective practice in urban water management. It gives a suggestion of use of a different - integrated approach, introducing two specific aspects of urban water planning: ...
Governing factors for motor oil removal from water with different sorption materials
(Journal of Hazardous Materials, 2008)
This paper has been focused on the sorbent efficiency for motor oil removal from water. Two types of sorbents were investigated: organic and inorganic. Natural wool fibers (NWFs) and recycled-wool-based nonwoven material ...
Temperature field in roller compacted concrete dams / Temperaturnu polje u gravitacionim branama od valjanog betona
(Savez građevinskih inženjera Srbije, Beograd, 2009)
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 ...
Određivanje trajektorije kamena u tekućoj vodi / Determination of a stone particle trajectory in the flowing water
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2002)
U ovom radu prikazana je metodologija proračuna trajektorije kamena u tekućoj vodi. Analizirani su faktori koji utiču na dužinu trajektorije, odnosno na vreme tonjenja i domet ispuštenog zrna. To su: početna dubina sa koje ...
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. ...
