Estimation of 1D-confluence model parameters in right-angled discordant beds’ confluences using 3D numerical model
(CRC Press/Balkema, 2016)
Parameters of 1D confluence models are originally defined for concordant beds’ (CB’s) confluences. This paper aims at estimating these parameters for discordant beds’ confluences using numerical simulation results of 3D ...
Hydrodynamic effects of debris blockage and scour on masonry bridges: Towards experimental modelling
(CRC Press/Balkema, 2016)
This paper describes the preliminary stage of an ongoing project investigating the hydrodynamic effects of debris blockage at masonry bridges. Debris blockage is cited as one of the primary causes of bridge failures in the ...
On the combined effect of bed elevation discordances in the main-river and the tributary in 90° straight-channel confluences
(CRC Press/Balkema, 2016)
The role of the difference in bed elevations in the main-river (ΔzMR) and the tributary (ΔzT) at their entrance to a 90° straight-channel confluence is studied numerically using a 3D finite-volume model. Three characteristic ...
Numerical simulation of 3D flow at 90o straight-channel confluence with bed elevation discordance
(TuTech Verlag, TuTech Innovation GmbH, 2012)
The paper aims at studying the effect of difference in bed elevations between the tributary and main canals (∆zT) on the flow in the confluence hydrodynamics zone. To do this, a 3D numerical model is used for flow simulation ...
Managing energy costs in water distribution systems
(Nis University, 2011)
The reduction of energy consumption is one of the first steps in fighting operational costs in Water Distribution Systems (WDS). Finding the optimal energy savings procedure and its implementation into a real-time control ...
3D numerical simulation of cross-levee breaching process due to overtopping flow
(CRC Press/Balkema, 2016)
Dike failures due to overtopping flows cause severe damages. For risk management, it is of great importance to understand the mechanism of dike failure and predict flows and sediment transport in the breaching process ...
Numerical modeling of dissolved oxygen recovery during aeration in lakes
(Environmental Hydraulics - Proceedings of the 6th International Symposium on Environmental Hydraulic, 2010)
One of available lake restoration technologies is injection of compressed air or oxygen into a hypolimnion, promoting vertical mixing of water and dissolution of oxygen.A numerical model has been developed for simulation ...
A review of the most commonly used methods for ungauged catchments flood flow estimation in Serbia
(12th International Multidisciplinary Scientific Geoconference, Sgem 2012, Vol. III, 2012)
This paper summarizes findings on the flood flow estimation in ungauged catchments during the last decade in Serbia. The method used for synthetic unit hydrograph ise well known in hydrological practice as SCS method. ...
Integrated hydrological information system for northern Algeria
(IAHS-AISH Publication, 2010)
As a result of cooperative work of experts from Algeria (ANRH) and Serbia (Energoprojekt with the assistance of Belgrade University) through the project CRESNA (Carte des Ressources en Eau Souterraines du Nord de l'Algerie), ...
A novel approach in numerical simulation of contaminant removal by air sparging
(Water Science and Technology: Water Supply, 2007)
The paper presents a mechanistic/deterministic model for simulation of mass removal during air sparging. From the point of numerical modeling, there are two issues considering air sparging: modeling of air flow and ...
