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 ...
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 ...
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 ...
Velocity field and discharge measurements at the turbine inlet of Iron Gate 2 hydropower plant
(European Geosciences Union/Copernicus Publications, 2021)
To define the performance characteristics of turbines in Hydropower Plants (HPP) accurate hydraulic, mechanical and electrical quantities are needed. The discharge is the most difficult quantity to measure and assess its ...
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 ...
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. ...
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 ...
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), ...
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: ...
Influence of small water storage reservoirs on reliability of irrigation water supply
(Macedonian Committee on Large Dams, 2021)
The paper analyses the consequences of climate change on the irrigation water demand and the impact of water storage reservoirs on increasing the reliability of irrigation water supply. Analyses were performed for the Vrbas ...
