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. ...
Novel approach to stream corridor restoration / Savremen način organizovanja u oblasti uređenja vodotoka i obnavljanja rečnih pojaseva
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2003)
The paper presents an organizational model for stream corridor restoration The key steps, such as: launching a restoration initiative, defining its scope, setting project boundaries and establishing planning and management ...
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 ...
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 ...
Numerical simulation of hydraulic consequences of dam failures on coal-ash disposal sites / Numerička simulacija hidrauličkih posledica havarija brana na pepelištima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2003)
The objectives of numerical simulation of hydraulic consequences of dam failure on coal-ash disposal sites are to define the scope of flooding consider possibility of early warning, and undertake the appropriate protective ...
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 ...
Numerical simulation of concentrated release of dredged sediments into the river / Numerička simulacija koncentrisanog ispuštanja izbagerovanog nanosa u maticu reke
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
This paper deals with prediction of hydraulic consequences of concentrated release of dredged sediments into the river using a two-dimensional numerical model. It is shown that flow, concentration, and siltation fields can ...
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 ...
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 ...
Application of 2D and 3D modelling in bay entrance design / Oblikovanje ulaza u zaliv primenom modela ravanskog i prostornog tečenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
Bays suffer from siltation, which is a natural process that cannot be avoided. The main cause of this process is mixing of the river-water containing suspended sediment and the river-bay water. High costs of maintenance - ...
