Numerical simulation of the three-dimensional flow at the confluence of the Sava and Danube Rivers
(Research Publishing Services, 2006)
In this paper, the confluence hydrodynamics at the mouth of the Sava and Danube Rivers in
the city of Belgrade is analysed by means of the three-dimensional numerical model. The
confluence offers excellent possibilities ...
Numerical simulation of 3D flow in right-angled confluences with bed elevation discordance in both converging channels
(Elsevier, 2016)
The paper studies a combined effect of bed steps (BS) in both converging channels on the 3D flow in a confluence with α = 90o. Nine combinations of bed elevation discordance ratio values in the two channels are analysed. ...
Effect of bed elevation discordance on momentum-flux from tributary flow and parameter values in 1d confluence models / Uticaj podvodnih kaskada na raspored protoka količine kretanja na ušću i vrednosti parametara u linijskim modelima ušća
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
Bathymetric surveys in confluences of both alluvial and mountaneous rivers have shown that a bed step at a tributary entrance to the confluence is a common morphological feature and that it may also develop in the main-river. ...
Effects of bed material grain-size distribution on bed morphology at a river confluence - numerical study
(EGU (European Geophysical Union), 2017)
River confluences play an important role in the drainage of a catchment and transport of sediments and pollutants within this area. Riverbed morphology at these important nodes of the river drainage network might be very ...
Can a 3D-Numerical Model be a Substitute to a Physical Model in Estimating Parameters of 1D-Confluence Models?
(Universidade do Porto, Faculdade de Engenharia, 2014)
A possibility of using a 3D-numerical model instead of a more expensive physical one for estimation of parameters in 1D-confluence models is considered. A set of existing experimental data from 90º confluence is used for ...
Numerical study of 3D flow at right-angled confluences with and without upstream planform curvature
(IWA Publishing, 2013)
The purpose of this paper is to study the individual and combined effect of upstream planform curvature and difference in bed elevations at the tributary entrance to the confluence on the flow in the confluence hydrodynamics ...
Numerical simulation of 3D flow in right-angled confluences with bed elevation discordance in both converging channels
(Elsevier Ltd, 2016)
The paper studies a combined effect of bed steps (BS) in both converging channels on the 3D flow in a confluence with alpha = 90 degrees. Nine combinations of bed elevation discordance ratio values in the two channels are ...
On the effect of bed elevation discordance in confluences with unequal channel widths
(EGE University, Izmir, Turkey, 2018)
The paper studies the effect of bed elevation discordance on the hydrodynamics in fixed-bed open channel
confluences where the tributary channel is narrower than the main channel and where the flow is subcritical. ...
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 ...
Uticajni činioci na rečnim ušćima sa izdignutim dnom pritoke / Controls at river confluences with discordant beds
(Savez građevinskih inženjera Srbije - Beograd, 2011)
U ovom radu se pomoću modela prostornog tečenja ispituje uticaj četiri izabrana činioca na hidrodinamiku ušća sa izdignutim dnom pritoke. To su: ugao uliva 'alfa', odnos sila inercije reke i pritoke MR, odnos [irina korita ...
