Numerical stability problems in hydrodynamic modelling of confluences with small junction angles
(Universidad de Concepción, 2009)
The paper addresses problems which arise from the use of 3D grids with quadrilateral faces on
the horizontal planes in hydrodynamic modelling of discordant beds asymmetrical confluences
with small junction angles. There ...
On the effect of the bed morphology on the river confluence hydrodynamics
(Proceedings of the International Conference on Fluvial Hydraulics - River Flow 2006, 2006)
A river confluence is known for the strong three-dimensional flow effects. The confluence hydrodynamics is significantly influenced by the river bed morphology. Two morphological features are typical for river confluences: ...
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 ...
Field measurement of small velocities / Merenje malih brzina u terenskim uslovima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
The application of 2D and 3D Computational Fluid Dynamics (CFD) modeling in open river flow is gaining in its popularity, especially in the field of sediment deposition on the river confluences and bay entrances. The ...
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 ...
Large Scale Particle Image Velocimetry: Measuring urban runoff / Large Scale Particle Image Velocimetry - merenje urbanog oticaja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
Measuring velocities and discharge in the field is well established hydrologic discipline essential for observing and studying the hydrological processes. Small discharges formed on urban areas during rain events are usually ...
2D modelling of water quality in bays / Modeliranje kvaliteta vode u zalivu primenom modela ravanskog tečenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
Contamination of river waters in terms of scale, intensity, and duration cause such severe problems that application of conventional engineering methods for environmental remediation projects is no longer adequate, and ...
Role of upstream planform curvature at asymmetrical river confluences–laboratory experiment revisited
(Kubaba Congress Department and Travel Services, 2008)
River confluence hydrodynamics is influenced by different controls such as the junction angle, bed elevation discordance between incoming streams, upstream planform curvature, momentum ratio values of the confluent streams, ...
Estimating the capacity of double side-channel spillways / Procena propusne moći dvostrukog bočnog preliva
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
A double side-channel spillway consists of two spillways, with channels joining into a common single branch, noting that for some specific site conditions such arrangements may suit better than the conventional one-side-channel ...
